The return usually is Json.

Where do I make a mistake? why is the api not working?
mistake (Argument #1 (not found) to ‘com.google.appinventor.components.runtime.util.YailDictionary.walkKeyPath(com.google.appinventor.components.runtime.util.YailObject,java.util.List)’ has wrong type (java.lang.String) (java.lang.String cannot be cast to com.google.appinventor.components.runtime.util.YailObject)
)

You are getting this error cause most probably you are not using api correctly or user id is not correct.
This is the correct way to get a response from that api. Debug your blocks with Do it and see

The results are in lists , so you have to use for each item in list block or for each number from … to … by … block or select a specific record using index in list
