jj git push fails with error stating "Error: early EOF"

[RoscoP]

Description

When running jj git push on a new commit in a new branch got an unexpected error that didn't indicate what was actually wrong.

Steps to Reproduce the Problem

I'm not sure how to independently recreate this issue, but this happened on a newly jj cloned repo (via https) and ran gh auth login. I imagine I'm not correctly auth'd or something similar due to the error message.

Does regular git push work? If you're not using a colocated repo, you can use git --git-dir .jj/repo/store/git push.

Got this

> git --git-dir .jj/repo/store/git push
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin master

To have this happen automatically for branches without a tracking
upstream, see 'push.autoSetupRemote' in 'git help config'.

> git --git-dir .jj/repo/store/git push --set-upstream origin master
error: src refspec master does not match any
error: failed to push some refs to 'https://github.com/RoscoP/winget-pkgs'

Try running jj git export before the git push, that should create all the branches in the git repo. Alternatively, you can create the master branch manually.

If you change things in Git, you will also need jj git import to get these changes before another jj git export will work.

In a co-located repo, these are done automatically for you.
