Hello,

I am running a function ‘dq_validate_model_integrity’ and ‘dq_validate_broken_references’ which give a 403 unauthorized error for a timeseries intermittently. There has been no change in access or data yet its failing sometimes with a 403 error.

Could you please let us know why this issue is coming up frequently?

PS: I have attached the screenshots of the passed and failed statuses of both functions with the timestamp as well as the logs of both failed functions.

 

Do let me know if there’s any more information required from my end.

 

Thanks alot :)

    Hi ​@Nikita Chandrashekhar Sawant  Could you please clean your handler.py of any sensitive data and post here? Each log is pointing to the handler.py at different lines.
