Log

Emits a structured automation log entry.

@lainstack/flow/log · Data

How to use it

Use this block to write one entry into the run log so a person can see what happened. It always continues on out. The output is empty, so no later block can reference it.

• level (info, warn, error, debug) only labels the entry. It does not fail or route the run. To stop the run, use @lainstack/flow/assert.
• The message must be 1 to 2,000 characters.
• The message and the optional details stay with the run. Do not put secrets in them.
• Use details for structured fields. It is a Record, and detailsSchema must describe it exactly.
• If the log cannot be written, the step fails with the retryable error log_emission_failed.
• To name the run in the Runs list, use @lainstack/run/set-details, not a log entry.
