Some headers are getting remove from the api response and status code changes

[clayrisser]

I created a custom api endpoint, and am returning some Set-Cookie and Location headers. However, it appears that they are getting dropped somewhere.

Below you can see the headers is in the response that I am returning.

But the header is not getting received in the response. Also the status code seems to be changed.

You can see in the screenshots that it is the exact same url and there are no responses with status 302.
