Calling a Custom Connector in a Canvas App



I have created a Canvas App.  I am trying to call a Custom Connector which can create a new MS Team using the MS Graph API, however when I call the Custom Connector Method from within the Canvas App, the request fails. 




PowerApp Canvas failed: { "error": { "code": "BadRequest", "message": "Write requests (excluding DELETE) must contain the Content-Type header declaration."


When I test the method in the Custom Connector, it works fine. I have tried adding content-type: application/json to the header request but when I check fiddler its never passed and hence fails.


All advice welcome!
