"Get All" API Error for "Unsupported content type" application/vnd.api+json

Not sure why I keep getting this error. Everything else seems to work. I receive a response with all of the data, queries work, but I can’t create the collection because of the error. Here is a copy of the response. I removed some of the content to save space (I’ll put [. . .] to show removed content). I’ve tried indicating in the header to only accept application/json or text/plain but it seems the only way the data comes formatted is application/vnd.api+json.


An error occurred when calling Get All
Unsupported content type: application/vnd.api+json

}

Same as here…

For me the solution was to declare the content-type in my webhook response

Hi all:
