fatal: Not a valid object name: 'main'.
The branch or commit doesn’t exist yet — typically in a new repo before the first commit.
Exact message you may see
Not a valid object name
Seen on:
Git
Meaning
Creating branches from main before any commit exists fails because main has no commit to point at.
Common causes
- No commits yet
- Typo in ref name
- Ref not fetched
⚡ Quick fix
- Make the first commit
- Fetch the ref
- Check spelling
Detailed fix by platform
Git
