# TooManyTopics (/docs/errors/chain/TooManyTopics)

The number of topics passed to `seal_deposit_event` exceeds the schedule's `event_topics` limit. Reduce the number of indexed topics in the contract's event definition or compare against the schedule limit.

Declared by the `Contracts` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).
