I get a recurring error in one of my automations. It only happens once every time we run the automation, the second time that we run it, we don’t receive the error. Is there a fix for this?

@Raul Jaimes I’m using OCR Capture Area after I open PDFs in Edge browser. This error only occurs the first time the bot runs, after it fails I no longer receive the message. It is very odd.

Try to add a big delay (5-10 secs)  before the action that throws exception.
