I like this pattern of being explicit that we are ignoring the error. However, is not a pattern that I've seen in the codebase.
I wonder if start adding here will create confusion.

My opinion is being that explicit about ignoring the error is a better (or at least more clear) pattern, and we've got to start somewhere! 😂 I'll do a quick temp check to see what some other folks think about this

That sounds like a plan. If we can get thumbs-up that we would like to make this a standard pattern moving forward, let's start here!

Consensus seemed to be:
- yes, explicitly acknowledging that we're ignoring errors is better than implicitly doing so
- we've had lots of trouble debugging tests specifically due to errors being discarded
- we should log the ignored error in this specific case, and whether to log or not is probably a case-by-case basis
- i'm also going to work on adding
errcheckto the linter so we can start to enforce this as a pattern going forward

Great, thanks for following up on this. All makes sense.
