Product Metafield with file type not returning url

Store Design

Topic summary

Developers are encountering issues accessing file-type product metafields in Shopify, where expected properties like .url don’t work as documented.

Core Problem:

  • File metafields return GID strings (e.g., gid://shopify/GenericFile/...) instead of generic_file objects
  • Direct property access like .url returns null or errors
  • Documentation doesn’t match actual behavior

Working Solutions:

  • Use | file_url filter: {{ product.metafields.namespace.key | file_url }}
  • Access via .value.url: {{ product.metafields.namespace.key.value.url }}
  • For list of files metafields, loop through .value array to access individual file objects

Additional Complications:

  • Different file types (images vs PDFs/audio) require different approaches
  • Email notification templates have additional limitations
  • Some users report intermittent “internal” Liquid errors

Current Status:
Multiple workarounds exist, but the issue persists across Shopify versions. One user submitted a documentation improvement request. The .value.url approach appears most reliable for single files, while list metafields require iterating through .value array.
