09/01/2022, 2:09 PMI got https://docs.prefect.io/api-ref/prefect/exceptions/#prefect.exceptions.ScriptError
This error while running a flow through cloud UI.
When I run the script using simple python flow it doesn't fail, but while running via deployment gives Script error.
Prefect as documented the error but not given what might be the probable solution

09/01/2022, 2:20 PMAre you able to show the code?

Pranit
09/01/2022, 2:21 PMcode within flow?

Jeff Hale
09/01/2022, 2:25 PMAh, sorry, I see there’s another thread you were working on with @Ryan Peden. If you can put all the details related to the current issue in this thread I think that would be helpful for the community and Prefect team as we try to assist.

Pranit
09/01/2022, 2:26 PMNo that issue was resolved
this is next issue coming after that
Which is strange and documented in prefect as exception but reason isnt listed

Jeff Hale
09/01/2022, 2:26 PMHmm. Gotcha. Can you please share the code and any command line commands and other relevant info here?

09/01/2022, 4:50 PMThank you the code looks like it might be helping us. Might be an issue with the airbyte integration.
We just released Prefect 2.3.1 today with a number of bug fixes. If you upgrade and recreate the deployment does it work then?
If that doesn't it work, it's possible you found a big in the prefect-airbyte collection and I would file an issue there: https://github.com/PrefectHQ/prefect-airbyte
