fix: make sure we handle empty values correctly

What: fix: make sure we handle empty values correctly

Why: We are getting some errors on Discourse related to this. These are not currently being reported to Sentry, here's the github issue if someone wants to take a look debtcollective/discourse-sentry#3

How:

• Update the code to handle empty values. We have this same code on the membership app, maybe there's an elegant way to extract this functionality.

Either way we are not gonna receive Sentry reports from any errors coming from this side, right?

[orlando]

Yeah, but the same errors we are getting here we're fixed on the membership app. We need to fix the sentry issue tho
