I 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

Can you please share the code and logs in this thread?

Are you able to show the code?
p
code within flow?
j
Ah, 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.
p
No that issue was resolved
this is next issue coming after that
Which is strange and documented in prefect as exception but reason isnt listed
j
Hmm. Gotcha. Can you please share the code and any command line commands and other relevant info here?

I have already pasted the error above. Scenario: 1. I am able to run the job using direct python command 
python /home/pranitsherkar/prefect/talend_fact_shopify_dailysales_productperformance.py
2. When I am starting an agent and executing the deployment through cloud

Thank 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
