# InsufficientInputAmount (/docs/errors/chain/InsufficientInputAmount)

Declared for swap inputs too small to execute, but no current code path raises it since the user-liquidity code was removed. If seen on an older runtime, check that the swap input amount is nonzero and large enough to produce output.

Declared by the `Swap` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).

## Remediation [#remediation]

Check the argument values against the operation schema

The same explanation is available in the terminal: `btcli explain InsufficientInputAmount`.
