Welcome to Microsoft Q&A! Thanks for posting the question.
It looks like you have deleted the deployment now as I couldn't find the function app. But looking into the backend logs I can see that you python function was generating below error:
No module named 'jiratosnowflake_convcode'.
Please refer to my private comment for full stack trace. I will suggest to verify this document to resolve the issue. You can verify the same from your application insight logs for your function app.
