Failed to run git diff: {}

Error message

Failed to run git diff:
{}

What it means

ensure! guard failing when a `git diff` variant (`--staged`, plain, or against a merge base) exits non-zero. The diff text cannot be produced, usually because a ref is invalid, the repository is corrupt, or the worktree is in a broken merge state.

Solutions

1. Examine git stderr in the error for the failing ref or object
2. Verify HEAD and the base ref exist (`git rev-parse HEAD <base_ref>`)
3. Check for an in-progress merge/rebase leaving the repo in a bad state
4. Retry after the user resolves repository state; the failure is usually transient or data-dependent

When it happens
