ERROR: Sorry, we couldn´t find any products. on Product List Page

This happens when our Facet URL Components contain special characters (e.g. *, ~, space ). 

for that, we can fix it by

Navigate to Commerce > Marketing > URL Components for Facets

Ensure that the URL Component includes characters that are not valid.

Note: Only dashes (-), underscores (_), and alphanumeric values are supported.
