Node Giving Unhandledpromiserejection Warning, When I'm *sure* I'm Catching The Rejection

I'm using node-libcurl. I've got a little module in which I have a queue for curl requests. Here's what the function looks like to actually make the curl request: const Curl = requ

Solution 1:

You're probably catching the reject on the queue and not on the stack. You get that error (warning) with the following code:

var p = Promise.reject("hello world");//do not catch on the stacksetTimeout(
  x=>p.catch(err=>console.log("catching:",err))//caught error on queue
  ,100
);

If you're going to catch the reject on the queue then you can do the following:

saveReject = p =>{
  p.catch(ignore=>ignore);
  return p;//catch p but return p without catch
}
var p = saveReject(Promise.reject("hello world"));//creating promise on the stacksetTimeout(
  x=>p.catch(err=>console.log("catching:",err))//caught error on queue
  ,100
);
