@TEMHITHORPHE Thanks for taking the time to report this!

The TypeScript code has a slight difference but it does not make any runtime benefit: https://github.com/slackapi/bolt-js/blob/%40slack/bolt%403.8.1/src/App.ts#L784-L790

Indeed, the lines of code are just redundant. We can simplify the code in future versions.

Okay, but I sure hope "redundant" is only what it is, cause I had to dig into source when I was getting a funny "slack_bot_authorization_error" on a recent(and first) AWS Lambda deployment days ago, brought the entire project to a standstill, and am currently just starting again from scratch, following the steps from https://slack.dev/bolt-js/deployments/aws-lambda like a baby, in case I missed any steps during my previous deployment. Needless to say that too just hit a snag, because for whatever reason I don't understand, "serverless-offline" is not responding to SLACK 's Event API's challenge, but that's an "issue" for another day.
