Could you please help to advise solution for try to solve it.

[Error exception in main thread] TalkException(parameterMap=None, reason='Internal error', code=20)

Start by reproducing the reported TalkException with code 20 after the line was updated, then inspect the resulting traceback and the code path that performs the update. The issue does not name a file or test; done means identifying the cause of the internal error and documenting or verifying a fix.
