Missing error handling/message when pushing an already existing tag

[PetraVesela]

In vanilla Git, you get a hint in such case:

error: failed to push some refs to '{repo}'
hint: Updates were rejected because the tag already exists in the remote.

When running git artifact add-n-push, the error message is rather cryptic:

Error in git rev-list --stdin --objects --not --remotes=origin --: exit status 128 fatal: bad object 2d23e65ec306f78c1827401882097d0fd71866dd
error: failed to push some refs to '{repo}'

Ohh .. interesting .. can you try to run with GIT_TRACE=1 git artifact ..

Sure, here's a redacted log:
