Laravel Vapor uploading images to s3 as json

Hi there.

For some reason, the application I'm working on is uploading images to s3 and tagging them with meta data of application/json.

Data that is being sent via signed-storage-url is..

{
  "content_type":"image/jpeg",
  "visibility":"public-read"
}

I'm really confused about why this is happening.

any suggestions?
