MaxCallDepthReached
A chain-side capacity limit was hit; reduce the size or count of the request
A nested contract call would exceed the maximum call stack depth defined in the pallet schedule. Inspect the cross-contract call chain for deep or unbounded recursion and flatten it or raise the configured depth.
Declared by the Contracts pallet; it classifies to the semantic code limit_exceeded.
