Having a CORS issue with updated version

Access to XMLHttpRequest at 'http://localhost:5678/rest/settings' from origin 'http://localhost:8080' 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'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

Running into this issue after updating my local codebase to the latest N8N. Not sure if someone could assist here. Had 480+ files changes.

Hey @BlameBlizz, welcome to the community!

CORS isn’t something handled by n8n directly but something checked by your browser: Cross-Origin Resource Sharing (CORS) - HTTP | MDN (mozilla.org).

It also seems there are two different pages involved here, I assume http://localhost:5678 is where your n8n listens? What is running on localhost:8080 and what exactly are you doing when running into this error?
