Passing Bearer Token "Can't Convert Access Token to JSON"

I put the token in header “Authorization”:”Bearer “ + mytoken

I do not include application/json header.

I use default settings in http request node except my return type “a parsed json object” which is expected return type. Can leave default UTF-8 to test

What I found helpful is to use PostMan. Get it working there and then do Code -> Dart - http and copy the Uri.parse for the url and copy var headers section minus the Cookie.
I then add this to a function node prior to my http node.
msg.url=“…”;
msg.headers={…}
