ChainIdMismatch

Check the argument values against the operation schema

The order payload's chain_id field differs from this chain's configured EVM chain id, e.g. an order signed for testnet was submitted to mainnet. Compare the order's chain_id with the runtime's pallet_evm_chain_id value and re-sign if needed.

Declared by the LimitOrders pallet; it classifies to the semantic code invalid_argument.
