Can't rebase onto latest

[b-chu]

There's no way to rebase stacked PRs onto the latest (or any) commit on main or dev.

Can you give more details? git spr update will rebase your current stack on top of origin/main

I get this stack trace when running that command

> git rev-parse --show-toplevel
> git fetch
> git rebase upstream/dev --autostash
> github fetch pull requests
> git log --format=medium --no-color upstream/dev..HEAD
> git branch --no-color
