Data shows in Composer, not app preview

I have an Airtable-linked app that pulls a collection - the data shows in Composer in the list component as an example, but nothing shows in the app or on the web for preview.

Hi there

I believe the view canvas preview just uses the schema from the REST data resource. Do you get any errors from the ‘test’-tab in your data resource config?

No… status is Green on both get collection and get record. It’s the typical “get a collection, select one from collection, and view the selected record on the next page” approach. I can get the collection to show, no problem - but the record on the next page just won’t work. I’ve tried making the repeated item {id} as an open page parameter, I’ve tried it as an app variable - but it doesn’t seem to be retrieving the record …I must be missing something more fundamental to working with data
