root cause:

per https://docs.bscscan.com/api-endpoints/accounts, action should be set to getBalanceHistory instead of getBalance

this is different than etherscan API

When using a contract or provider event listener, the listener will NOT catch any logs if there are multiple topics in the filter.
Ex. 1:

const filter = {
	address: contract_address,
	topics: [
		utils.id('Transfer(address,address,uint256)'),
		utils.hexZeroPad(address, 32)
	]
}

This will not catch any logs/events at all. Whereas just one topic will work as expected.
Ex. 2:

const filter = {
	address: contract_address,
	topics: [
		utils.id('Transfer(address,address,uint256)')
	]
}

This returns the expected transaction. I have tried with more topics, null placeholders, and ensured proper formatting. When using the second provided filter, the topics in the returned transaction match exactly what the topics of the first filter would look like.
I was stumped on this for a long time before I switched to a BscScan JsonRpcProvider where the first filter worked as intended. Thanks!

For some reason, it's working when I'm testing this on my local machine.
But when I deploy to lambda it fails with the following error.

Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.5.0)
