Some background which may help debug.

I ran "snapcraft register links" a week ago which told me it was already registered.
I requested that links be transferred from zyga to snapcrafters

So now there's two links in the store, one attempted to be registered by me (snapcrafters) and one registered by zyga and transferred by the store team.

I spoke to Adam Conrad who revoked the request I'd made initially, but the snap still doesn't show up when we do "snapcraft status" when logged into the store as the snapcrafters user.

Alan actually spoke to me, not infinity.

The root cause of this issue is that there are two package declarations for the 'links' name, both owned by the snap advocacy team.

The store API is returning the one with the revoked name when queried for account-information by snapcraft which is then choking on the missing snap_id (because, luckily, there is no snap associated with the revoked name).

The store side bug is allowing this situation to occur. We will discuss options to unblock this particular instance and then fix the general case to not allow us to end up here again.

I am seeing the same issues with snap lpshipit [0].

Other snaps registered to the same account work fine.

[Celso Providelo (cprov)]

The problem should be fixed for both `links` and `lpshipit` snaps, the conflicting name-dispute request was removed.

[Philip Roche (philroche)]

I confirm it is now working for lpshipit.

Thank you

[Kyle Fazzari (kyrofa)]

Proposed fix for the snapcraft CLI to stop dumping a traceback in this situation: https://github.com/snapcore/snapcraft/pull/2115

[Celso Providelo (cprov)]

The general API guidelines are kept and snapcraft is handling with any error in a more appropriate way now.
The data organization problem in the Store, duplicated records for revoked & approved names, is tracked in https://bugs.launchpad.net/snapstore/+bug/1778493.
