Properly type queries and extrinsics

import { Registration } from '@polkadot/types/interfaces/identity/types'

The issue only identifies an import from @polkadot/types/interfaces/identity/types and does not name a file, package, query, extrinsic, or test. Start by locating the query and extrinsic definitions that use this import, then identify the relevant type-checking or test entry point; done should mean those APIs are properly typed and the existing checks pass.
