Update custom field configurations function often crashes


I’ve tried to update a custom field configuration using the Jira Cloud REST API from my Forge application.
But the function is unstable and often crashes with an error.
In my tunnel logs, I see the next message.

(Use `node --trace-uncaught ...` to show where the exception was thrown)

And the Jira page displays an “Error server response: 503” message instead of UI elements related to the update configuration function.

Could anybody help me solve this issue?
