CORS Issue When Using Authorization Header
I encountered a CORS issue when trying to make API calls from a webpage. The webpage initiates two requests to the backend: a preflight request and a fetch request. My server handles the preflight request correctly, but the fetch request still results in a CORS issue.
Interestingly, the fetch request always occurs before the preflight request. Could this reverse order be causing the CORS issue?
When I do not use the authorization header, the request seems simpler and only involves one request, which includes the origin information, and this does not result in a CORS issue.
I am using RapiDoc for documentation with the following docs.html setup:
<html>
<head>
<title>RapiDoc</title>
<!-- needed for adaptive design -->
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1">
