Base path in server url or parameter not correctly handled

[previ]

Description

OpenAPI definitions with server url with a base path (example: "http://localhost:8080/v1" are not correctly handled (error 404 or 500).

Expected behaviour

Correctly handle the API with full path (server url + API path)

Actual behaviour

Server raise exception, return 404 error code (or 500 in running with uvicorn):

% curl http://localhost:8080/v1/hello/world
{"type": "about:blank", "title": "Not Found", "detail": "Not Found", "status": 404}

or with uvicorn:

{"type": "about:blank", "title": "Internal Server Error", "detail": "The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.", "status": 500}

Steps to reproduce

Use the code in this gist, run it with the command:

connexion run openapi.yaml --host 0.0.0.0 --port 8080

or

uvicorn main:app --host 0.0.0.0 --port 8080

Additional info:

It works if the server url is amended with base path and the base path "v1" is put in the API path.

Output of the commands:

• python --version Python 3.11.6
• pip show connexion | grep "^Version\:" Version: 3.0.3

Seems to be caused by starlette 0.33.0 which was released a few days ago.
Downgrade to 0.32.0.post1 make it work again.
