Notes

  • Authentication required. You must be logged in before fetching logs.
  • App context required. Run from a linked project, or pass --app-id / set BASE44_APP_ID.
  • When multiple functions are specified, logs are merged and sorted by timestamp.
  • If --function is omitted, logs are fetched for all functions in the current app.
  • The --limit applies after merging logs from all specified functions.
  • The --since and --until values are normalized to UTC if no timezone is provided (appends Z).
