Endpoint returning an image

[joakim-emagine]

Has anyone has any luck with an endpoint that returns an image?
I get the error:

Argument 2 passed to Muffin\Webservice\Webservice\Webservice::_transformResource() must be of the type array, null given, called in .../vendor/muffin/webservice/src/Webservice/Webservice.php

You might have more luck returning it as a string. Use something like a base64 encode to convert it to a string and then it could be returned in json, if you're web service responds with json.

Otherwise I think an image would be returned as a response.
