This is because there is no type for "MimeType['image/jpg']". You just only need to add "MimeType['image/jpeg']" to allow uploading files with either .jpg or .jpeg extensions.

It works with jpeg, but when I send jpg it gives an error

when I specify each type, it validates correctly, but if I use image/*, it gives an error in startsWith

can you disable the validation and log the request body

it should displaying like this on terminal:

{
  file: FileData {
    originalFileName: '19ce4743-bcdd-4eb7-807b-e35206a33887-1.sketchpad.jpeg',
    fileName: '1743044796315-19ce4743-bcdd-4eb7-807b-e35206a33887-1.sketchpad',
    fileNameFull: '1743044796315-19ce4743-bcdd-4eb7-807b-e35206a33887-1.sketchpad.jpeg',
    encoding: '7bit',
    mimetype: 'image/jpeg',
    fileExtension: 'jpeg',
    fileSize: 229418,
    hash: '064dc76dccfdef2335064162d748d24a',
    buffer: <Buffer ff d8 ff e0 00 10 4a 46 49 46 00 01 01 01 00 90 00 90 00 00 ff e2 01 d8 49 43 43 5f 50 52 4f 46 49 4c 45 00 01 01 00 00 01 c8 00 00 00 00 04 30 00 00 ... 229368 more bytes>
  }
}

when it displaying like this :

{
  file: '19ce4743-bcdd-4eb7-807b-e35206a33887-1.sketchpad.jpeg'
}

make sure you change the request enctype to multipart/form-data on your request for sending file to server

[jongomes]

Yes, I'm using postman to test, if I remove the validation it works correctly, but I would like it with validation

I believe the problem is in the jpg extension, with jpeg OK

The problem is actually when it doesn't send the property in the form-data

For example, you expect file, and postman doesn't send it, it breaks when image/*, but it doesn't break when it's image/jpeg

https://codesandbox.io/p/devbox/dazzling-austin-f8s2x5

so @isnotempty() is not caught

Work me, close issue

[jongomes]

The request is fluctuating when it is in .jpg format, I have to send it 3 times for it to work
