I am using a javascript pre middleware to return a 400 response if a required url parameter is missing.
// should fail and stop chain
request.ReturnOverrides.ResponseCode = 400;
request.ReturnOverrides.ResponseError = "Invalid app Id";
The endpoint am using expects an xml body and has the right content-type: text/xml
header set. The problem I have is that this always returns a json error body, where I expect that my error_400.xml
will be rendered.
Anything am missing, maybe about the intended use of ReturnOverrides?
