Product Metafield with file type not returning url

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.

It is indeed something strange and the documentation need to be improved. I submitted a report on that documentation page.

In the meanwhile the only way that I was able to get the file URL path was using this

File URL: {{ product.metafields.specs.pdf_file | file_url }}
