A simple Flask server with connexion cannot be distribuate with pyinstaller

Question

Context

I’m trying to distribute my python server that uses connexion with pyinstaller.

Unfortunately, the executable product not pyinstaller does not work. Of the first request an error 500 is issued while it is not in "normal" mode.

INFO:     Uvicorn running on http://0.0.0.0:8080 (Press CTRL+C to quit)

INFO:     127.0.0.1:56490 - "GET /swagger/ui/ HTTP/1.1" 500 Internal Server Error

I created a simple server available on GitHub: repository

The question

Does anyone know why I have this error and how I can correct it?

I tried changing the server url and changing when the API is initialized, but it didn't change anything.

The aim would be to be able to distribute a server with a simple executable on any linux system.
