(Unrelated to your question, but I assume that 'git tree' is an alias of
'git log --oneline --graph' by the looks of it).

Yes, this is because you're asking to rebase your branch onto the parent
of 1e99034, which doesn't exist because 1e99034 is the "root" commit and
therefore has no parents.

'git rebase' has a special option for exactly this case, which is
'--root'. By replacing '1e99034^' with '--root', you should be able to
do what you want.

Thanks,
