I merged this, but ended-up reverting, as the isMissing is already handled in the types (

boom/lib/index.d.ts

Lines 198 to 204 in c2293a2

	interface MissingAuth {
	/**
	* Indicate whether the 401 unauthorized error is due to missing credentials (vs. invalid)
	*/
	isMissing: boolean;
	}

), and this change actually made boom's type tests fail. If we want to make a change like this I think it requires a closer look.

@devinivy I do apologize. Will definitely be more careful next time!

No worries! I missed it too. I am not sure why CI didn't run properly for this PR, but I think that would have cleared it up pretty quickly for us.
