I have searched GitHub for the issue.

Describe the Scenario

I have tried to update the cover of a shelve with the API.
I use the Insomnia client for this.
If i send an "normal" put request with json data in the body, the update of name, description, books and tags works fine.
But if i send a multipart request to update the image, nothing will be updated. Not the name, not the description, no other field.
These are the props from the docs:

In a Multipart Request it's not possible to send an array.

I hope someone can help me, to solve my problem.
