# invalid_signal

> Signal webhook: a value in the alert has the wrong type or is out of range.

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

HTTP 400. Nothing reached the broker.

**Likely causes:**

- A number field holds text, or a field holds a JSON object or list.
- risk_pct above 100, a size of 0, or a percent that is not above 0 and at most 100.

**What to do:** Fix the field the message names. Nothing was sent.

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