# unknown (/docs/errors/unknown)

The error did not match any known chain error name or message pattern.

The original message is preserved in the diagnostic; read it for details. if it names a chain error that should be classified, the mapping lives in bittensor/error\_map.py.

## Chain errors [#chain-errors]

No chain error classifies to this code — it is raised client-side by the SDK before or after the call reaches the chain.

The same explanation is available in the terminal: `btcli explain unknown` (or `btcli explain <ChainErrorName>` for one exact chain error).
