chunk upload fails towards the end and errors out - but video is successfully uploaded

Chunks seem to always fail to upload towards the end, somewhere between 80% and 95% (depending on the size of the video), and then the error event eventually gets thrown, but in the dashboard I can see the video has successfully uploaded.
Here's a screenshot:

solved by @geneticgenesis, the fix was to use the cors_origin argument when creating the upload URL, which I was omitting.
