Could not extract session ID from path: {:?}

Error message

Could not extract session ID from path: {:?}

What it means

anyhow error from the resume branch (crates/goose-cli/src/cli.rs) when --path was supplied and Path::file_stem() returns None or the stem is not valid UTF-8. file_stem fails for paths whose last component is '..' (no stem) or a path like '/'; to_str() fails for non-UTF-8 bytes in the filename.

Solutions

1. Pass the full path to the session .jsonl file, not a directory: --path /path/to/20250325_200615.jsonl
2. Avoid '.', '..', and '/' as the path value
3. If the filename has non-UTF-8 bytes, rename the file to a UTF-8 name first
4. Prefer the modern form instead: --resume --session-id 20250325_200615

Example fix

# before
goose --resume --path ~/goose/sessions/

# after
goose --resume --path ~/goose/sessions/20250325_200615.jsonl
goose --resume --session-id 20250325_200615  # preferred

let ok = path.is_file() && path.file_stem().and_then(|s| s.to_str()).is_some();
if !ok { /* reject early: pass the .jsonl file path, not a directory */ }

fn usable_session_path(path: &Path) -> bool {
    path.is_file() && path.file_stem().and_then(|s| s.to_str()).is_some()
}

When it happens

Trigger: Passing --path ., --path .., --path /, or a legacy session file path whose filename contains non-UTF-8 bytes. Normal '/path/to/20250325_200615.jsonl' works; only degenerate or non-UTF-8 paths hit this error.

Common situations: Passing a directory instead of the .jsonl file (e.g. --path ~/goose/sessions/), shell glob expanding to '..' or an empty result, filenames with invalid encoding after a filesystem migration.
