Upload task fails for large file size

[najeebanwer]

I am trying to convert a video file from MPG to MP4 and it works fine for smaller files. When I try to upload a large file (3.14GB) it fails with this error:

POST https://storage.cloudconvert.com/tasks failed: Cannot write more bytes to the buffer than the configured maximum buffer size: 2147483647.

My code is:

I know that uploading and converting this large file works fine on the CloudConvert website, so I'd like to know how to avoid this issue when using the API. Is there a way to modify the "maximum buffer size"?
