Answer 1

The error SyntaxError: Unexpected token < likely means the API endpoint didn't return JSON in its document body, such as due to a 404.

In this case, it expects to find a { (start of JSON); instead it finds a < (start of a heading element).

Successful response:

  
  
    {"foo": "bar", "baz": "qux"}
  

Not-found response:

  
  
    
Not Found
    
The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.
  

Try visiting the data endpoint's URL in your browser to see what's returned.
