Can not rebase to first commit

I can not rebase to first commit.

This is how to reproduce:

kes@work ~/work/projects/general/Auth $ git tree
* 67857d5 (HEAD -> dev) asdf
* 1e99034 (local/dev) Initial commit
kes@work ~/work/projects/general/Auth $ git rebase -i --autostash --rebase-merges 1e99034^
fatal: invalid upstream '1e99034^'


git --version
git version 2.30.0
