Infamous `PollingBlockTracker` error

[pathornteng]

Description

Hi team, I am getting the following error when trying to deploy a medium - large smart contracts. Even though Truffle returned error, the transaction was actually successful. I can reliably reproduce the problem from deploying a smart contact in this repo. https://github.com/hashgraph/hedera-fxprocessor-demo/tree/main

/Users/pathorn/Work/hedera/hedera-fxprocessor-demo/web/node_modules/eth-block-tracker/src/polling.js:51
        const newErr = new Error(`PollingBlockTracker - encountered an error while attempting to update latest block:\n${err.stack}`)
                       ^
Error: PollingBlockTracker - encountered an error while attempting to update latest block:

@pathornteng is this still the case? With large contracts there's limited options but we'll keep exploring how to avoid the latency that causes the confusion
