Access-Control-Allow-Credentials headers not being set on localhost on 10.2.2

firebase-tools:10.2.2

MacOS

[REQUIRED] Test case

Running a local express server that hosts an API on port 5001. Frontend runs on port 3000. The express is correctly configured with the cors middleware which accepts localhost:5001 and localhost:3000. The request failed due to:

"Access to fetch at 'http://localhost:5001/px-platform-dev-a1ec4/us-central1/api/v1/auth/login' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'."

This could have something to do with #4227 but I'm not sure.

[REQUIRED] Steps to reproduce

See above

[REQUIRED] Expected behavior

The request should pass preflight. This is not an issue with [email protected]

[REQUIRED] Actual behavior

It fails preflight so nothing get's logged to the terminal.

Would you mind posting a minimal repro of your server and maybe also HAR files? This can help us look into the headers
