TypeError: Cannot read properties of undefined (reading 'map')

Hi @teolemon
I’d like to investigate this issue.
It looks like results.products may be undefined in some edge cases, causing the .map() call to throw.

I can try to reproduce the scenario locally and add a safe guard or proper fallback handling if needed.

Please let me know if I may proceed. Thanks!

Hi @VaiTon

I’ve submitted a fix for this issue in PR #1016.
The update adds a safe guard to prevent calling .map() onresults.products when it is undefined, which was causing the Sentry TypeError.

Please let me know if any adjustments are needed. Thanks!
