Failed to find Server Action "x"

[qdev0]

Summary

in production I keep getting

"[Error: Failed to find Server Action "x". This request might be from an older or newer deployment. Original error: Cannot read properties of undefined (reading 'workers')]"

which then completely destorys backend of the app then users can't even login or logout or perform any other actions.

when i rebuild the project and it passes the ci/cd and deploys it for some time works without problems then in couple of hors this happens randomly. I haven't been able to find anything related to this as well. anyone have any idea how to solve this?

Additional information

[Error: Failed to find Server Action "x". This request might be from an older or newer deployment. Original error: Cannot read properties of undefined (reading 'workers')]

Example

No response

[qdev0]

Also. the action name is "x" not a random id like other issues. and I can't replicate this in dev envrionment or manually triggering action on production. This just happens randomly at some point.

I am self hosting on a vps with docker

Yep, just got this as well. Application went down with timeouts (no crash, just infinite loading) accompanied by a spam of that log. Running on 15.1.9.
