I didn't need to set a "file_tye" when uploading? Is there something I am missing?

I am using code similar to https://github.com/Lepozepo/S3/issues/133 I only noticed this error recently I have tried to run that code before and it worked. Previously my s3 was working fine one file at a time.

Removed personal info:

S3.config = {
  key: '..',
  secret: '...',
  bucket: '...'
};

The problem from #133 seems to be for only single upload. I just use the multiple upload part of the code for even single uploads...
