# alert_time_required

> Signal webhook: this webhook has a max alert age, so the alert must say when it fired.

Source: https://tickwire.io/docs/errors/alert_time_required/

HTTP 422. Nothing reached the broker.

**Likely cause:** max_alert_age_s is set and the alert message has no time.

**What to do:** Add `"time": "{{timenow}}"` to the alert message, or clear max_alert_age_s. Nothing was sent.

**Retry:** No. The same request gets the same answer; change something first.
