request.interceptors mapimagelayer working

The request headers aren't being sent on MapImageLayers.  but works with FeatureLayers
token = 'sometoken';
api = 'myproxyserver';
  urls: [`https://${api}v1/GIS/proxy`],
  before: (params) => {
    params.requestOptions.headers = {'Authorization': 'Bearer ' + token};
  headers: {'Authorization': 'Bearer ' + token}

looks like it's not being sent with the fetchImage function within MapImageLayer.js ...

I think this is related to the responseType of the esriRequest:

When this value is image the headers and timeout options are ignored.


esriRequest - RequestOptions - responseType 

request | API Reference | ArcGIS API for JavaScript 4.9 


If this is the case, we will consider making an enhancement at a future release.

Hi Nathan, looks like we have this fixed for the upcoming 4.10 release, due out in mid-December. The "headers" will now be honored when the value type is "image". Hope this helps.
