+
+To fix this, first generate a new API key from the [Guardrails Hub](https://hub.guardrailsai.com/keys). Then, configure the Guardrails CLI with the new API key.

+```bash
+guardrails configure
+```
+
+There is also a headless option to configure the CLI with the token.
+
+```bash
+guardrails configure --token <your_token>
