ots_getTransactionBySenderAndNonce returns null for most recent transaction

[sealer3]

System information

Erigon version: Most recent 3.x

OS & Version: Linux

Commit hash: ba0129d

Erigon Command (with flags/config): (Erigon with an HTTP rpc server and the ots namespace enabled)

Consensus Layer: (any)

Consensus Layer Command (with flags/config):

Chain/Network: Ethereum mainnet

Expected behaviour

ots_getTransactionBySenderAndNonce returns the correct transaction hash for the latest nonce sent by address addr, as in Erigon 2.x.

Actual behaviour

ots_getTransactionBySenderAndNonce returns null for the latest-nonce transaction of a given sender.

Steps to reproduce the behaviour

1. Find any Ethereum transaction sender
2. Find the last nonce of an included transaction by this sender
3. Call Erigon via JSON-RPC using that sender and the last nonce of the sender (this example might become out of date but is the one that was used for testing):

curl -X POST \
 http://localhost:8545 \
  -H 'Content-Type: application/json' \
  -d '{
        "jsonrpc": "2.0",
        "method": "ots_getTransactionBySenderAndNonce",
        "params": ["0x58B79418e46327E2269AB8A14D309D8C3a2a57Da", 233],
        "id": 1
      }'
