The Flashblocks RPC had a bug where it would panic if
getTransactionByHashwas used to load historical deposit transactions.These transactions did not exist in the mempool (system transaction) and did not exist in the cache (historical transaction) but in the case of deposit transactions we would always try to fetch a receipt from the cache to populate
deposit_receipt_versionanddeposit_nonce.Since we did
unwrap()without an error check in that path, it would cause a panic.This PR attempts to fix that by pre-loading the deposit transaction receipt from
eth_apiin case a historical deposit transaction is attempted to be fetched viagetTransactionByHash.Edit; ignore the branch name. i thought the root cause was a race condition, it was not.
