07/11/2023, 9:18 PMHello 👋 I have gotten a few flows today that have failed when the state of the flow is trying to update. I’ll post the error in the thread
Copy code
State message: Flow run encountered an exception. PrefectHTTPStatusError: Server error '503 Service Unavailable' for url '<https://api.prefect.cloud/api/accounts/><account_id>/workspaces/<workspace>/task_runs/<task_run>/set_state'
Response: {'exception_message': 'Service Unavailable'}I left out my account_id, workspace and task run id. It looks like issues with the Prefect api, but I was not sure if this was happening across other accounts
I’ve had this pop up a few more times today again, wanted to see if anyone else was experiencing this

07/12/2023, 5:37 PMHi John, it looks like there are some invalid characters happening in your code, and it’s failing to write to teh cloud database
Copy code
(sqlalchemy.dialects.postgresql.asyncpg.Error) <class 'asyncpg.exceptions.CharacterNotInRepertoireError'>: invalid byte sequence for encoding "UTF8": 0x00image (21).png

07/12/2023, 5:38 PMOhhhh that looks like a duplicate DML from snowflake
Okay that makes more sense. Thank you
The logging in the prefect UI did not show me that so that helps me out a lot

07/12/2023, 5:39 PMYea, I think this was a good call out all the same, we are debating if a 503 is the right return here
503 implies a server side error (which it is) but as a result of a bad input which was client input, so it threw me off here

07/12/2023, 5:40 PMYep that’s what I thought it was an issue on prefects side, but now that I know it’s on our end I can fix the issue
