As far as I know on prem you can only publish it with the power-shell script on the NAV service tier.
In cloud there is a page 2507 "Upload And Deploy Extension" that is used to deploy the app, but this only works for SaaS.
If you look at this link below, there are different option to do this, but they all require admin rights on the NAV service tire machine. :-(
A very interesting situation, it is strange why an error appears, I would like to help, but my knowledge is not sufficient for this yet. You have not found a solution to this problem? thanks
