Error in TMDb API: JSON data abruptly ended

Currently, I am attempting to parse JSON data that is being returned by The Movie DB. Unfortunately, I keep encountering an error message indicating the following:

Uncaught SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at XMLHttpRequest.movieReq.onreadystatechange (discover.js:34)
    at loadIMDBDetails (discover.js:38)
    at MainFunc (discover.js:68)
    at discover.js:5
The issue arises when I try to access individual movie information through this XMLHttpRequest:

movieReq.open('GET', '', false);

I have other XMLHttpRequests which successfully retrieve JSON data without any problems. These requests utilize the discover function of the API.

Below is the function causing the problem:

function loadIMDBDetails(mO, i) {
    movieReq = new XMLHttpRequest();

    movieReq.onreadystatechange = function () {
        var parsedObj = JSON.parse(movieReq.responseText);
        mO.imdbId = parsedObj['imdb_id'];
    };
    movieReq.open('GET', 'https://api.themoviedb.org/3/movie/299537?api_key=34f8307d9addabf7924eab7f22cabb23', false);
    movieReq.send();
}

When utilizing console.log to display the responseText, the output is as follows:

{"adult":false,"backdrop_path":"/w2PMyoyLU22YvrGK3smVM9fW1jj.jpg","belongs_to_collection":null,"budget":152000000,"genres":[{"id":28,"name":"Action"},{"id":12,"name":"Adventure"},{"id":878,"name":"Science Fiction"}],"homepage":"",...}

Answer №1

After realizing my mistake, I discovered that I had forgotten to include a check for the onreadystatechange event in my code. By adding the necessary check and implementing the json parse within an if statement, I was able to successfully resolve the issue!

movieReq.onreadystatechange = function () {
    if (this.readyState == 4 && this.status == 200) {
        var parsedObj = JSON.parse(movieReq.responseText);
        mO.imdbId = parsedObj['imdb_id'];
    }
};

After running

console.log(movieReq.responseText)

, do you receive the accurate JSON data before the line:

var parsedObj = JSON.parse(movieReq.responseText);

If this is the case, then there's no need to use the JSON.parse() function. You can directly access any element of the movieReq.responseText object. For example, you could retrieve movieReq.responseText.imdb_id without parsing it since it is already in JSON format.

JSON.parse() is only required when converting a string into a JSON object. For more details, refer to: https://www.w3schools.com/js/js_json_parse.asp
