PVA Error Code

Hi all, I've seen several error codes when creating chatbot but can't identify what is the reasons / solutions of the errors. Anyone can share experience here? 


Error code 2001 

Possible cause: unknown


Error code 2003 

Possible cause from testing: format of the variable in MS Power Automate flow. E.g score should be a number/float and not as an integer 


Error code 2008 

Possible cause from testing: User clicked Login but failed to enter the validation code within 4 minutes.


Error code 2020 


"You can also go to the flow itself (by clicking the link in the PVA topic) and see what happen on it's run history.  

This is often caused because the flow was changed since it was added to PVA. Removing and adding it again might solve if this is the issue. 

 PS: If you run this same topic in the test bot within PVA, you will get a clearer error message explaining it's the flow. But you will still need to go to the flow itself to see what happened."
