Failed to stage: {}

Error message

Failed to stage:
{}

What it means

ensure! guard failing when `git update-index --add --cacheinfo` (staging the freshly hashed blob into the index) exits non-zero. It means the blob SHA produced by hash-object could not be written into the index for the given path — typically a corrupted or locked index, or a SHA/path mismatch.

Solutions

  1. Inspect the embedded git stderr for reasons like 'index file smaller than expected' or lock file contention
  2. Remove stale .git/index.lock if present and retry
  3. Run `git status` to verify index integrity
  4. Fall back to a normal `git add` of the path if index manipulation keeps failing
Defensive patterns

Strategy: try-catch
