Question

Hey everyone just updated to 2 4 2 and all my flows stop working did I miss a braking change The error is Response detail protected block types cannot be updated The strange thing is that the block that is accessed is of type local file system and I do not have such block in my system

here is the complete log with a stack trace produced after I run a deployment from the UI

Anna Geller · Answer

rather than logs it would be more helpful to first share how did you get there how did you configure your agent API server which versions are there I believe some component in your setup might be still on the old Prefect version as this release should fix the protected block types issue <https github com PrefectHQ prefect blob main RELEASE NOTES md release 242>

Georgi Yanev · Answer

let me double check are all docker images changed

Anna Geller · Answer

generally since I don t see any immediate breaking change that could cause that perhaps you could at first to avoid further issues in your flows downgrade to a lower version and to help identify the root cause of why this upgrade didn t work it might be best to create a GitHub issue so we could help troubleshoot on Monday

Anna Geller · Answer

gt The strange thing is that the block that is accessed is of type local file system and I do not have such block in my system based on this message one thing you could try regardless of whether you decide to keep 2 4 2 or downgrade is to delete the deployment s that failed and create new ones

Anna Geller · Answer

potentially also recreating blocks

Georgi Yanev · Answer

it was easy to recreate all blocks and deployments but still the same will downgrade for now

Georgi Yanev · Answer

actually digging deeper your suggestion that part of the system was running an old version was spot on

Georgi Yanev · Answer

some of the flows are defined in software and use docker infrastructure too and there the image was not updated to use the 2 4 2 version

Georgi Yanev · Answer

thanks for pointing me in the right direction

Anna Geller · Answer

great work figuring that out
