From the reference under HttpDo:

Method for executing an HTTP request. If data type is not specified, p5 will try to guess based on the URL, defaulting to text.

I suggest you provide the datatype when calling the function and see if this solves your issue.

The user info level is undefined probably because you dont have a json object in the first place. As soon as you solve the first issue, this one would work off the bat.
