The JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string. An optional reviver function can be provided to perform a transformation on the resulting object before it is returned.
You are trying to parse json from your response (string). something like JSON.parse('<!doctype html...')
Your server is not returning an application/json data
