[SyntaxError: Unexpected end of input] while trying to get IG posts

[jatinseth2007]

Hello,

I am trying to fetch IG posts of the users by using the method

var def = Q.defer();

ig.user_media_recent(user_id.toString(), {
count: 10000
},
function (err, medias, pagination, remaining, limit) {
if (!err) {
def.resolve(medias, pagination);
} else {
def.reject(_common_worker.generate_worker_error(err, {
error_type: 'IG',
ig_id: user_id,
message: "Error in fetching data from Instagram api get_user_post_timestamp method"
}, __filename));
}
});
return def.promise;

But for some users the control always go in ELSE part with error shown below:

[SyntaxError: Unexpected end of input]

I have done some digging in error, i have found that i am getting right data from Instagram but I am getting incomplete JSON object in "pagination" var in else method: I am getting the response ended like ", "profile_picture": "https://scontent.cdninstagram.com/t5"

+1 - I am starting to see this.

I'm seeing this where in call, req.on('end' is firing before the actual end. body.length < parseInt(res.headers['content-length'], 10) and I get a JSON parsing error. If I prevent the JSON parsing under this condition, I am shortly thereafter greeted with ECONNRESET.

Can we redo the call in case of end firing early?

[jatinseth2007]

Okay, so what could be the solution for this case ? what could we do to prevent it ?

Adding some sort of if statement check like I previously suggested, could prevent the JSON.parse error, and instead hit the ECONNRESET. Then, in your application code, you can handle the error similarly as you would any 500 error. My limited understanding is that ECONNRESET is caused by the other end (Instagram, in this case) closing the socket unexpectedly. Personally, I'd consider that along the lines of a 500. -shrugs-
