Hello, I use this docker image with python support Docker
And I have an error message Error fetching feature flags ReferenceError: AbortSignal is not defined when using PythonFunction. The process freezes for 10 seconds, and the result of the test script is displayed correctly, but this error occurs in the log.
Can it come from my nginx proxy manager reverse proxy?
Error 1:
