UnverifiedPulse

Declared for drand pulses that fail validity checks, but current code raises PulseVerificationError for verification failures and silently skips unverified pulses. If seen on an older runtime, check the pulse signature against BeaconConfig.

Declared by the Drand pallet; it classifies to the semantic code invalid_argument.

Remediation

Check the argument values against the operation schema

The same explanation is available in the terminal: btcli explain UnverifiedPulse.
