InvalidSchedule

The pallet's schedule is misconfigured, e.g. a zero weight or zero ref_time_by_fuel for a basic operation, making gas conversion impossible. This is a runtime configuration issue; inspect the Schedule constant rather than call arguments.

Declared by the Contracts 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 InvalidSchedule.
