Same error here, if I start a connexion3 dev server (uvicorn) and the port is already used. It only happens when justMyCode is set to false. Here is a sample project: connexion3_helloworld.zip It is basically a copy of this project: https://github.com/spec-first/connexion/tree/main/examples/helloworld

`ConnexionMiddleware.run` is optimized for development. For production, run using a dedicated ASGI server.
