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
