How to troubleshoot post upgrading from 2017.1 to 2018.2.3, a workflow throws "Save Image :System.NullReferenceException: Object reference not set to an instance of an object" error?
Post upgrading from 2017.1 to 2018.2.3 one of the existing workflow which was working earlier, throws error "Save Image :System.NullReferenceException: Object reference not set to an instance of an object".
And this error doesn't happen if the workflow is run directly from the Robot machine.
[Below are some of the reasons identified]
- If selectors for Take screenshot activity are used, then remove the selectors and attempt again
- Also try to add some 2-3 mins delay in between Take Screenshot and Save Image activities and verify
