Description of bug

I currently face issues with fetching block information via polkadot websocket endpoint (using substrateinterface lib in Python) for blocks with specific transaction type, here are few samples:

Block number : 21473809
Transaction type : convictionvoting (remove_vote)
Error text: ValueError: Index '20'' not present in Enum type mapping

Block number : 21473810
Transaction type : balances (transfer_allow_death)
Error text: RemainingScaleByteEmptyException: Decoding - Current offset: 108 / length: 148

I would be grateful for any help

Steps to reproduce

ENDPOINT= "wss://rpc.polkadot.io"
endpoint = substrateinterface.SubstrateInterface(url=ENDPOINT)
block_info = endpoint.get_block(block_number=21473810)
block_info
