Description

I am uploading file from frontend to get URL but when I upload the file with multer, it automatically changes the file type on the backend.

I used word changes here because the file type shows correct on the frontend. For example: the file I am uploading is of type

{
path: "2023-12-14 13-19-55.mkv"
type: "video/x-matroska"
lastModified: 1702539348430
lastModifiedDate: Thu Dec 14 2023 13:20:48 GMT+0545 (Nepal Time) {}
name: "2023-12-14 13-19-55.mkv"
size: 17555107
}

But on the backend it shows:

{
  fieldname: 'imageData',
  originalname: '2023-12-14 13-19-55.mkv',      
  encoding: '7bit',
  mimetype: 'application/octet-stream',
  destination: 'uploads/',
  filename: '1712392840374-2023-12-14 13-19-55.mkv',
  path: 'uploads\\1712392840374-2023-12-14 13-19-55.mkv',
  size: 17555107
}

Why does it change the file type?
