remote commit message was empty

Error message

remote commit message was empty

What it means

This error is thrown when the remote commit-message generation endpoint returns a 200 response whose `message` field, after trimming whitespace, is an empty string. The library treats an empty message as a failed generation rather than producing an empty commit message, so it aborts with this error. It guards against committing with a blank message when the AI/remote service technically succeeded but produced no usable text.

Solutions

  1. Check the raw response body (curl the same endpoint) to see if `message` is truly empty or the field name changed
  2. Verify API credentials/quota on the remote commit-message service — empty completions often indicate throttling or an expired plan
  3. Update to a matching API version / field schema so `message` is populated
  4. Retry generation, or fall back to a locally-generated commit message instead of the remote one

Example fix

// before
let message = payload.message.trim().to_string();
if message.is_empty() {
    bail!("remote commit message was empty");
}
// after
let message = payload.message.trim().to_string();
if message.is_empty() {
    eprintln!("remote commit message was empty; using fallback");
    generate_local_commit_message(diff)
} else {
    Ok(trim_quotes(&message))
}
Defensive patterns

Strategy: fallback

Validate before calling

// peek before trusting the remote message
let body = resp.text()?;
let payload: RemoteCommitMessageResponse = serde_json::from_str(&body)?;
if payload.message.trim().is_empty() {
    eprintln!("remote returned empty message; will use local fallback");
}

Type guard

fn has_message(p: &RemoteCommitMessageResponse) -> bool {
    !p.message.trim().is_empty()
}

Try / catch

match generate_remote_commit_message(&diff) {
    Ok(msg) if !msg.trim().is_empty() => msg,
    Ok(_) | Err(e) => {
        eprintln!("remote message unavailable ({e}); using local fallback");
        generate_local_commit_message(&diff)
    }
}

Prevention

When it happens

Trigger: Calling the commit-message generation flow whose HTTP response parses into RemoteCommitMessageResponse with `payload.message` being "", whitespace-only, or missing/JSON-null (deserializing to empty after trim).

Common situations: Remote AI service returns an empty completion (e.g. prompt produced no output), a proxy strips the body, an API version change renamed the message field so it defaults to empty, or rate-limited/quota responses return an empty message with 200.
