"Error: Variable must be of type object" on new machine

Recommended Posts


I've been using autoit for about a year now and overall it's been great despite my limited understanding of all of its features. I have several scripts that run on virtual machines that have been running smoothly for several months without any issues. Recently, I had to create new virtual machines and migrate my scripts over and now I am getting errors that I can't seem to repeat, but seem to happen at least once a day with all of my executables that were flawless before.

The error that I keep getting is:

Autoit Error

Line [this number varies per script] (File "[path to my executable]"); Error: variable must be of type object.

I  never received this error before until I moved everything to the new VMs, and when I rerun my scripts after clearing the error everything seems to work and run fine until hours later or sometimes the next day. I am assuming that that the root cause may be in some kind of settings on the VM itself since it is happening nearly across the board, but I have no idea where to even look. These are running on Windows 7, which is what they were running on before I had any errors.

The only consistent include used in these scripts is  IE.au3

Has anyone run into a similar problem or can maybe point me in the right direction. I am at the point of pulling hair out trying to resolve this. I have even rewritten and re-compiled the scripts to see if somehow the executables got corrupted, but that didn't help.

Thank you.

@AJB the error is telling you exactly what is wrong - you're calling a variable that is not an object. Unfortunately, more than that is impossible if you do not post your script.

 I have a similar problem but I received this error when moved from Windows 7 / IE7 / 32bit to Windows 7 / IE11 / 64 bit machine.

The script selects one of  4 dropdown options in the loop and randomly the third or fourth gets this error when in FireBug you can see all of them and if

_IEFormElementOptionSelect() is not called, Console write will print all of them

Here is the code:

$oForm = _IEFormGetObjByName($oIE, "myform")
$tp = _IEFormElementGetObjByName($oForm, "target")
If @error = "0" Then
    $cc = 0
    _IEAction($tp, "focus")
    For $t In $tp
        $cc = $cc + 1
        ConsoleWrite("count: " & $cc & @CRLF)

        If $cc = 1 Then
            ConsoleWrite(_IEPropertyGet($t, "outerhtml") & @CRLF)
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            ;If ($t.innerText) <> "" Then
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            _IEFormElementOptionSelect($tp, "Coldstore", 1, "byText")
        ElseIf $cc = 2 Then
            ConsoleWrite(_IEPropertyGet($t, "outerhtml") & @CRLF)
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            ;If ($t.innerText) <> "" Then
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            _IEFormElementOptionSelect($tp, "Windows File Share/SMB", 1, "byText")
        ElseIf $cc = 3 Then
            ConsoleWrite(_IEPropertyGet($t, "outerhtml") & @CRLF)
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            ;If ($t.innerText) <> "" Then
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            _IEFormElementOptionSelect($tp, "Internal SD card", 1, "byText")
        ElseIf $cc = 4 Then
            ConsoleWrite(_IEPropertyGet($t, "outerhtml") & @CRLF)
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            ;If $t.innerText <> "" Then
            ConsoleWrite("innerText: " & $t.innerText & @CRLF)
            _IEFormElementOptionSelect($tp, "none", 1, "byText")



count: 1
<option value="coldstore">Coldstore
innerText: Coldstore
innerText: Coldstore
count: 2
--> IE.au3 T3.0-1 Error from function _IEPropertyGet, $_IESTATUS_InvalidObjectType
"C:\Program Files (x86)\AutoIt3\Include\IE.au3" (1115) : ==> Variable must be of type "Object".:
For $oItem In $oItems
For $oItem In $oItems^ ERROR

You can see that I commented check for an empty string.

If I uncomment it, I won't receive the error "Variable must be of type "Object".:" but I won't be able to select all options in loop in the dropdown.

The output will be with the 2 options available and 2 empty strings:

count: 1
<option value="coldstore" selected="">Coldstore
innerText: Coldstore
innerText: Coldstore
count: 2
<option value="wfs">Windows File Share/SMB
innerText: Windows File Share/SMB
innerText: Windows File Share/SMB
count: 3
--> IE.au3 T3.0-1 Error from function _IEPropertyGet, $_IESTATUS_InvalidObjectType
count: 4
--> IE.au3 T3.0-1 Error from function _IEPropertyGet, $_IESTATUS_InvalidObjectType

Any help will be appreciated!!!!!!

Welcome to the AutoIt forums.

When you post code please use Code tags - see here how to do it.  Then you get a scrolling box and syntax colouring as you can see above now I have added the tags.

      I have a few questions:
      I am using Oracle Application Testing Suite's OpenScript 13 (Eclipse IDE), Oracle Java 6, and AutoIt.
      My goal is to access a given Internet Explorer browser window (`$ieTitle`), send the keystroke of "shift-control-s" for "Save As" functionality to be invoked, so that I can download a (PDF) file to a given location ($fileName).
      The code within the script `DownloadPdfFile.au3` is
      $ieTitle = $CmdLine[1] $ieControl = "AVL_AVView31" $fileName = $CmdLine[2] ControlFocus($ieTitle, "", $ieControl) ControlSend($ieTitle, "", $ieControl, "+^s") ; Save as dialog $winTitle = "Save As" ; wait for Save As window WinWait($winTitle) ; activate Save As window If Not WinActive($winTitle) Then WinActivate($winTitle) ControlFocus($winTitle,"","Edit1") ControlSetText($winTitle,"","Edit1",$fileName) Sleep(2000) ControlClick($winTitle,"","Button3") Exit 0 So I compiled it with SciTE-Lite (32-bit Version 4.4.6 , creating `DownloadPdfFile.exe`, and so within my Java code, I have
      String command = autoItExePath + " " + scriptPath + " \"" + winTitle + "\" " + directoryPath.toFile().toString() + "\\Form9Report" + sdf_ddmmmyyyy.format(new Date()) + ".pdf"; try { Process process = Runtime.getRuntime().exec(command); process.waitFor(); } catch (Exception e) { logger.error("Exception " + e.getMessage(), e); } The output would be like `C:\Program Files (x86)\AutoIt3\AutoIt3.exe C:\...\AutoItScripts\DownloadPdfFile.au3 "https://****.com/****.exe?temp_id=**** - Internet Explorer" C:\...\Report05Apr2022.pdf"` which does run without the $cmdLine successfully. 
      When executed by Java, I see in the taskbar an icon, which I right-click has "[Check] Script Paused" and "Exit".
      (1) How do I unpause the script?
      (2) How do I avoid having the script paused?
      Any help is appreciated.

      Hi all,
      I've been using the following code for many years for the sole purpose of tracking my app usage via Google Analytics:
      ;GOOGLE ANALYTICS $AppStatsName = @ScriptName $GA = _IECreate("https://mywebserver/apps/stats/" & $AppStatsName & ".html", 0, 0, 0, 0) The app simply calls a blank .html page on my webserver which only contains the GA tracking code.
      The $iVisible parameter is set to "0" in my case, which means the IE browser is invisible to the user.
      I noticed in Windows 11, the URL is called in the Edge browser and is not invisible.
      So, I wonder if anyone out there has any suggestions on calling a URL invisibly on any operating system?

      I am looking to create a script which refreshes/reads a webpage every few seconds. My goal is to see if the page has changed, then I will send myself a notification that the webpage has been updated.
      However, rather than downloading the entire webpage every single time, is there a way to check when the webpage last updated?
      If not, is there away to partially download/read html source until a specific tag is hit?
      Goal: I would like to increase my poll rate and not excessively waste data.

      But I miss something and the code not works as intendend.
      Please join and contribute, in solving this issue, as this will be handy for entire community.
      I think that this may be realated to ChrB() which I simply translate to StringToBinary()
      Especialy this :
      StringToBinary(Chr(0))) could be the main issue.
      But for now I'm tired and going to sleep.
      Hope maybe tomorrow somebody solve this issue.

      Am trying to automate injecting credential on the login form for all kind of Web application for IE. I know how to identify the form name by viewing the source code and using the method - _IEFormGetObjByName($ie, $form_Name).
      I would like to know how to identify or get the form object for the web app where there is no form name tag for example below, for the is I have used - _IEFormGetCollection($ie, 0) to get the form object.
      My Question is does it work for all kind of application "_IEFormGetCollection($ie, 0)" how to identify Index value? is it always 0? is there any better solution?
      The final solution am looking for is find out form object, get the username, password field and inject credential and submit the form.
      How to find out index value? for the forms which does not have form name field.
      $login_form = _IEFormGetCollection($ie, 0) $email_field = _IEFormElementGetObjByName($login_form, $form_UserName) $pass_field = _IEFormElementGetObjByName($login_form, $form_password) $login_button = _IEFormElementGetObjByName($login_form, $form_submitbutton) _IEFormElementSetValue($email_field, $CmdLine[2]) _IEFormElementSetValue($pass_field, $CmdLine[3]) ControlSend($hwnd, "", "[CLASS:Internet Explorer_Server; INSTANCE:1]","{Enter}") OR This works fine if the form has form name. $login_form = _IEFormGetObjByName($ie, $form_Name) $email_field = _IEFormElementGetObjByName($login_form, $form_UserName) $pass_field = _IEFormElementGetObjByName($login_form, $form_password) $login_button = _IEFormElementGetObjByName($login_form, $form_submitbutton) _IEFormElementSetValue($email_field, $CmdLine[2]) _IEFormElementSetValue($pass_field, $CmdLine[3]) ControlSend($hwnd, "", "[CLASS:Internet Explorer_Server; INSTANCE:1]","{Enter}")
