Shopify Apps

Topic summary

Users are encountering two distinct error types in the Google Merchant Center affecting product listings:

Image Link Errors:

  • Products show “Invalid Attribute Value [image link]” in the Google app, though images display correctly on websites and in Google search results.
  • Google requires specific image formats (JPEG, WebP, PNG, GIF, BMP, TIFF) and accessible URLs.
  • Potential causes include robots.txt file blocking image directories or URL accessibility issues.
  • This error may prevent products from appearing in Google Shopping.
  • Status: No clear resolution provided in the thread.

Unit Pricing Measure Errors:

  • Hundreds of products flagged with “Invalid whole number [unit pricing base measure]” and “Invalid real number [unit pricing measure]”.
  • Google recently changed these previously optional fields to required.
  • Working Solution: Create feed rules in Google Merchant Center:
    • Navigate to Products > Feeds > Content API > Feed Rules
    • Add rules for both unit_pricing_measure and unit_pricing_base_measure
    • Set both values to “1ct” for items sold per unit
    • Test changes before applying
  • Users report that updating values directly in Shopify doesn’t resolve the error; changes must be made in Merchant Center via feed rules.
  • Status: Resolved for users who implemented the feed rule solution.
