<p>If a browser wants to do CORS on GET, then it's usually some
unneeded request header causing that. See the CORS-safelisted
request headers here:

·
We have implemented Open Street Map and It works great though.

We are facing some challenges while accessing Open Street Map API from our endpoint.
·
The error is as follows: CORS Error :

You need to be more specific about what you are doing and what CORS
headers exactly your software is expecting. The only recent change is
that we don't send access-control-allow-methods anymore with GET
requests but that should be according to spec.
We also send a 204 instead of 200 but that really shouldn't trip your
code.
