Context.Reference<boolean>Context reference that routes the built-in default logger and TTY pretty console logger to stderr.
When to use
Use to route built-in logger output to stderr while keeping stdout reserved for protocol messages or data output.
Details
The reference defaults to false. Providing true makes the affected
loggers call console.error instead of console.log.
