This one needs environment variables set before it will start: FS_ACCESS_TOKEN (Access token from your own registered FamilySearch application. The place gazetteer and collection catalogue work without one.), FS_ENV_FILE (Env file to read settings from and to re-read a refreshed token from mid-session. Defaults to the nearest .env from the working directory upward.), FS_CLIENT_ID (Your registered application's client id, reported by auth_status.), FS_ENVIRONMENT (production, or integration for the FamilySearch sandbox.), FS_TIMEOUT (HTTP timeout in seconds.). The author declared them in the registry entry; get the values from the project itself.
