Describe the bug
I have a unit test to test rate limits that requires two stub responses. The first one is to get an OAuth token (200 - access token) to authorize a request, and the second one which returns a 429. When I run the test from Visual Studio or CCI, the test fails because the response status is 400 instead of 429. However, when I use Fiddler (which I used for debugging) the test works just fine, and I'm not able to reproduce the issue.
Expected behavior:
I expect the test to return 200 with access token for the first call (this works fine), and then a 429 instead of 400.
Test to reproduce
The exact test code to reproduce it is public and can be found here.

It is a strange bug. It seems that the request is invalid and is not handled by WireMock?
I will take a look.

I think I found your issue.
This mapping is setup like:
However WireMock.Net will return the access_token as defined, so with \r\n and with spaces.
This response is added to headers using this code:
localVarRequestOptions.HeaderParameters.Add("Authorization", "Bearer " + token);And apparently RestSharp breaks on the \r\n.
Because when I do this: token.Replace("\r", "").Replace("\n", "") it works.
(Probably Fiddler tries to repair the data which is probably the explanation that it works with fiddler)
The next issue is that the errorLink is not valid json:
