Getting error " x is an undeclared prefix. Line 2,position 12692 " when running a bot using orchestrator

Hi,

Could anyone please help me with this.
When i run my bot for the first time using orchestrator it is running perfectly. But when i run it for the second time using orchestrator it is failing in the middle and getting the error " x is an undeclared prefix. Line 2,position 12692 ". Please find below the screenshot for the same.
I am not using any xml at all but getting an xml exception.

Thanks,
Abhishek

Are you doing an excel automation?

I also had such an error, after successfully run the workflow. when I checked my input excel file, an error message shows that ‘excel file is not in the readable format. and there is an option to recover it if we trust the source.’ I deleted the excel and created the same again and the error is corrected.
