Hello, so you will want to debug your collection queries, here are a few ways you can try that:
hard code a value you know exists into the contains() and see if anything returns
remove the contains and see if you can just return all of your data
double check your collection ID, permissions
try eq() if contains isn’t working for you
Once you are sure you are returning data from the collection with hard coded values, you can start to add the other code back one piece at a time and make sure each step is working
