Errors
Produce human-friendly errors from your tasks
When a task fails, surfacing an error message to the user who ran your task can help them debug what
went wrong without spelunking through logs or pinging the engineering team. Airplane supports a
convention for producing errors from tasks that integrates with the rest of Airplane.

Errors are returned from tasks through Output via the following convention:

If a task produced an error, the output UI will render the error's message:

Producing errors
Errors can be produced by throwing an error. All uncaught errors will be automatically converted
into error output and a stack trace will be printed in the run logs. When a task fails, any
ongoing child tasks will be cancelled.

Errors can be produced by logging Output. Make sure you wrap
your error message in double quotes so that it is a valid JSON string.
