Access to fetch at ‘http://localhost:5000/api/web/create’ from origin ‘http://localhost:3000’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: Redirect is not allowed for a preflight request.

The browser precedes the request with the OPTIONS method. The server is returning a 308 Permanent Redirect for the request and is therefore not considered CORSable.
cause
- Server side
@app.route('/api/web/create/', methods=["GET"])
- client-side
fetch(APIROOT + "web/create", {...})
- So this is redirecting access without the trailing slash to a URL with one.
solution
fetch(APIROOT + "web/create/", {...}) I just didand it solved the problem.
