failed to take screenshot when in unattended mode

Posted on by johnaustin

anyone experienced a inconsistent behaviour of taking a screenshot during a flow when in unattended mode.

I get an error, 'unable to take screenshot' , does not happen all the time !

I am using the screenshot as a way of debugging, so having the debugging code fail is not helpful 🙂

thanks

@johnaustin are you trying to take screenshot of an entire screen or just a window? Also try adding timestamp to filename name just to make sure there is no overwrite conflict when saving the file.
Can you share more details on error from Power Automate logs?

It fails on all combinations of primary screen, all screens etc.

error is not that helpful

{
    "outputFlowErrors": {
        "localizedName": "Error",
        "value": "Failed to take screenshot.",
        "variableName": ""
    }
}

I am curious if anyone has found a solution to this issue. If i run the flow in attended mode the @screenshots work perfectly, when I run the same flow in unattended mode the screenshots are not what they are supposed to be, or what they are in attended mode. Why does it always take a @screenshot of the wrong thing in unattended mode? absolutely infuriating.

thank you.

@JoaquinHome , add Wait stages and focus on the correct window is absolutely necessary for the appropriate screenshots.
