Hi all! Can it be that something has changed since the last prefect cloud maintenance? All my deployments created before the maintenance are running fine but the one added after is failing with

AttributeError: 'Flow' object has no attribute 'retry_delay_seconds'

when I run it from the UI with a "Quick run" option. And if I choose a custom run and set the retry delay (that's theoretically optional) I get

AttributeError: 'Flow' object has no attribute 'version'

Hi @Alex Litvinov - thanks for flagging! Can you give a bit more information so we can try figure out what's happening? 1. What version of prefect are you running? (What is shown when you run

prefect version

?) 2. Where do you see the "AttributeError" message? Is it in the logs from your flow run? Or elsewhere? 3. What happens if you run from the cli using

prefect deployment run '<flow-name>/<deployment-name>'

4. How are you creating your deployment? (Are you using the

prefect deploy command

or

prefect deployment build

or the python method?) 5. Is it at all possible your flow or deployment was created during the maintenance period? What happens when you try to redeploy and run it?

Hi @Jenny, apologies for delayed response, I didn't get a chance to re-check it earlier And now it seems to be fixed, I can't reproduce this behavior any more. Do you think the information you've requested is still valuable?

Thanks for confirming! I think we’re good but let us know if you run into any further issues.
