Strapi uploads into a repeatable component are not linked to file

System Information
  • Strapi Version: "4.3.3
  • Operating System: macOS 12.2.1
  • Database: mysql
  • Node Version: 16.13.0
  • NPM Version: 8.1.0
  • Yarn Version: 1.22.19

I have a collection that looks like this:

field1 (string)
details (repeatable-component) {

photo (file field)


to upload the image into the “photo” filed, I am creating formData from frontend application with following name files.details[0].photo

formData.append( files.details[0].photo, photo, )

The file gets uploaded and is visible in the media library, but not linked to the photo field inside the collection. What am I possibly doing wrong here?
