There was a problem hiding this comment.
Because handleKeyringRequest either throws SnapError or Error , the middleware doesn't catch it as FormatError, hence the "Invalid format: " prefix gets stripped

Explanation
Original PR & reviewer comments here: MetaMask/snap-bitcoin-wallet#645
Migrates the Bitcoin snap to the v2 Keyring API and declares the corresponding capabilities in the manifest. Also removes all v1-only keyring methods and replaces the manual routing table with the v2 dispatcher.
