TooManyUIDsPerMechanism

A chain-side capacity limit was hit; reduce the size or count of the request

View as Markdown

Setting max UIDs or mechanism count would make max_uids times mechanism_count exceed the chain default of 256 UIDs per subnet. Check MaxAllowedUids and the subnet's mechanism count so their product stays within the limit.

Declared by the SubtensorModule pallet; it classifies to the semantic code limit_exceeded.
