WebRequest: How to ignore wrong response content type?

Im using a WebAPI from a widget. One of these requests is a authenticate request passing an auth token and the response is returning an bearer token.

The problem is, that the response it using "content-type: application/json" as responde header, but the body is plain text.



I filled the options with this setting to force a plain text response.


        var options = {
            :responseType => Communications.HTTP_RESPONSE_CONTENT_TYPE_TEXT_PLAIN,
            :method => Communications.HTTP_REQUEST_METHOD_POST,
            :headers => {
                "Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED,
                "Authorization" => "Bearer "+ mAccessToken
            }

That is working on a fenix 5xplus, but on fenix6, fenix7 or Epix, a responsecode -400 is returned instead.

Can I somehow ignore that content check? It's fine if Garmin wants to help to check for corrent type, but in this case it's very frustrating. I can't change the WebAPI and I cant get the Garmin API to use my given option as content type.

How can I solve this problem?


Edit:
I got answer from the WebAPI owner:
The body is a valid JSON (string).
So my question is:
Why am I getting an -400 error when using JSON as result content-type?

        var options = {
            :responseType => Communications.HTTP_RESPONSE_CONTENT_TYPE_JSON,
            :method => Communications.HTTP_REQUEST_METHOD_POST,
            :headers => {
                "Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED,
                "Authorization" => "Bearer "+ mAccessToken
            }

Response body:

"eyJhbGciOiJSUzUxMiIsI..."

Travis.ConnectIQ: Is this an expected error or is it a bug? Shouln't the data result be teh parsed string when using HTTP_RESPONSE_CONTENT_TYPE_JSON?


Edit:
I'm wondering if this is an error which only is present in the simulator.
It seems, that the JSON string is parsed correct in the device with option HTTP_RESPONSE_CONTENT_TYPE_JSON.
But it returns an error -400 in simulator.

I made a fallback function if JSON option results in -400 error to try again with option HTTP_RESPONSE_CONTENT_TYPE_TEXT_PLAIN to get it workin in simulator. But that's a bit ugly.
Could this someone from Garmin please test and confirm? Many thanks!
