Typed Transactions with Access List

When sending a raw transaction which contains access lists (ie, transaction type 01, EIP-2930) to https://relay.flashbots.net, method `eth_callBundle`, the relay returns error 400 with message `unable to decode txs`. Removing tx type, the request goes through just fine.

Is this expected? Are access list transactions not supported?

Start by reproducing the raw transaction request against https://relay.flashbots.net using eth_callBundle, comparing an access-list transaction (type 01, EIP-2930) with the same request without the transaction type. Determine whether the relay is expected to support access-list transactions and document or fix the `unable to decode txs` response.
