# InvalidDerivedAccountId (/docs/errors/chain/InvalidDerivedAccountId)

Deriving the pure proxy account id from the provided entropy failed to decode into a valid account. Check the spawner, `proxy_type`, and `index` arguments used with `create_pure` (or the equivalent lookup when destroying one).

Declared by the `Proxy` 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 InvalidDerivedAccountId`.
