The error Variable¶

In TBL, error contains information about an error that was caught by the ! command.

It is only available when an error occurs during command execution.

How error Works¶

• When a runtime error happens, the ! command is triggered
• Inside the ! command, error becomes available
• error describes what went wrong

This allows you to handle failures safely.

What error Contains¶

The error variable is an object that may include:

• Error message
• Error type
• Stack information
• Execution details

Important Notes¶

• error is available only inside the ! command and HTTP call fallback command on error
• It is read-only
• It exists only during error handling

The error variable helps you debug issues and show user-friendly error messages.
