# LicenseCapabilityMissingError Class

Error thrown when a public API method is called for a FeatureId that the current license entitlement does not grant, or when the license key itself blocks every gated feature (a missing or invalid key, an expired classic key, or a trial past its grace period); the message then names the key's state instead. Mirrors gate B's ErrorMessage.LicenseCapability, but this one guards the API surface itself rather than a formula evaluation, so it is thrown synchronously instead of surfacing as a cell error.

This list names every method that can throw it - resumeEvaluation is deliberately NOT among them: it is the sole exit from a suspended engine, so gating it could strand an instance permanently if the entitlement changes mid-suspension (see the note on HyperFormula. ensureCapability).
