xmlHttprequest getting called with “OPTIONS” method only
I make a request to server (an API call) from one server and it is cross-origin resource so I expect options request.
For option request I am getting below response headers:
access-control-allow-headers: 'all headers I sent'
access-control-allow-methods: GET,OPTIONS
access-control-allow-origin: *
content-length: 0
content-type: application/json
date: Mon, 19 Nov 2018 09:14:32 GMT
status: 200
x-amz-apigw-id: some id
x-amzn-requestid: 'some id'
When response header is returning:
access-control-allow-origin: *
I get an error:
Access to XMLHttpRequest at
'APIURL' from origin 'http://localhost:4200' has been blocked by CORS policy:
Request header field X-Application is not allowed by
Access-Control-Allow-Headers in preflight response.
Then why request with method was not made?
Whereas another API to same server with same response for options request work with get method.
I am using angular7 and backend servers has enabled CORS.
Can someone guide me why this is happening, what changes I can make?
Thanks!
UPDATE:
I removed X-APPLICATION header from request headers as per comment from "sideshowbarker". But still get below error below error for 2 API, whereas others API from same origin to same server works fine:
- Access to XMLHttpRequest at 'APIURL server 1' from origin
'http://localhost:4200' has been blocked by CORS policy: Response to
preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. -- Server1 from local host
- Access to XMLHttpRequest at
'API URL server2'
from origin 'http://localhost:4200' has been blocked by CORS policy:
Response to preflight request doesn't pass access control check: It
does not have HTTP ok status.
If server is configured to handle CROSS origin request then I should not get this error. I will grateful if someone help me understand and solve this.
If someone wants to help, let me know if more details are required.
Thanks!

The 'APIURL' server/endpoint needs to be configured to include 'X-Application' in the access-control-allow-headers value. It’s not currently configured to do that. Otherwise you wouldn’t be getting that error message.

Thaks @sideshowbarker for help. I removed that header and that error went away. What if I don't get "Access to XMLHttpRequest at 'APIURL' from origin 'localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. " whereas server returns access-control-allow-origin: *.
