Unable to publish snap to any channel

Hi folks, I am currently working on my first snap and so far I was able to get it working on my system and also the builds seem to pass now on all platforms. But I am unable to do a release to any channel. On the website the controls are greyed out / do nothing and when I use the cli I get the message

Snap cannot be published due to inconsistent state.

Any ideas what I’m doing wrong?

Thanks! Julian

I managed to figure it out myself after reading some threads here. The issue was a problem which I discovered via the dashboard : )
