How can I access an object in a complex JSON file as follows?

Question

I am trying to access the events object array found in the JSON file gotten from this API: http://app.ticketmaster.com/discovery/v1/events.json?keyword=Madonna&apikey=fU1iKOy83W5ewGCIGQmW8I6FIPvOG8de

I have tried accessing the events object using this following logic :

   useEffect(() => {
    const fetchData = async () => {
      setIsLoading(true);
    const result = await axios(url);

    setData(result.data.events);
    setIsLoading(false);
    };

    fetchData();
  }, [url]);

<Button onClick={() =>
            setUrl(`http://app.ticketmaster.com/discovery/v1/events.json?keyword=${query}&apikey=fU1iKOy83W5ewGCIGQmW8I6FIPvOG8de`)
          }
            className={classes.button} color="primary">Search</Button>

Here is the JSON format in which the document appears

It generates the following error: TypeError: Cannot read property 'events' of undefined

Answer 1

console.log(MainObject._embedded.events[0].locale) //en-us

Answer 2

You're accessing events directly from data which is undefined.

You likely need to use:

result["_embedded"]["events"]
