Nexus3 repository reject ".ipk" files derivated from the Debian package

We have artifacts with .ipk extension, a package format that is derivated from the Debian package.
We have an issue due to uploading this kind of file, either with Maven or Raw repository.

The return message from Nexus :

Detected content type [application/x-debian-package, application/vnd.debian.binary-package], but expected [application/vnd.shana.informed.package]: test.ipk

I would suggest raising an issue in the ‘dev - nexus’ project at
