Looking for help troubleshooting

[ipullrank]

Hello!

First thanks to @phanan for building both Koel and this add on to be able to use S3 buckets. Very cool projects that I'm hoping to get a lot of use out of and hopefully ultimately contribute to.

I followed the instructions (which may need to be updated a bit due to updates to the Lambda interface) and nothing is showing up in Koel:

I looked at the issues on this repo and didn't see anything that sounded relevant. So then I looked at the Lambda messages and they all are returning this error message:

{
"errorMessage": "Could not determine the media type."
}

The files are all mp3s so I'm not really sure where to start with troubleshooting this.

Please advise. Thanks!
