Hey @Wakil18 - thanks for sending over the snippet, that helps a lot.
This does look very similar to another thread we’ve seen where the product Resource Picker returns no results after a Collection filter is applied when the picker was opened with a filter.query. We logged that one internally as a possible bug on September 2, 2025, and the last public update I can see was November 14, 2025. Does that sound like the same behaviour you’re hitting here? (community.shopify.dev)
Just as a note as well , our current App Bridge direction is the CDN-loaded App Bridge flow, so if this app is still using an older app-bridge-react setup, I can’t fully guarantee identical behaviour there. (shopify.dev)
If you’re up for one quick test, could you try the same picker config without the filter.query and let me know if the Collection filter starts working again (just by setting the other filter variables)? If it does, that’d help confirm this is the same underlying issue. Our current Resource Picker docs do support filter.query, so that’d be a useful repro point for me. (shopify.dev). Hope to hear from you soon!
