Issue with productSet Mutation for Boolean Metafield on Products with Variants

Products and Orders APIs
1

Hi,
I am using productSet mutation to update a metafield of type boolean. The setup is correct, including the key and namespace, and it works perfectly for products without variants. However, when I try to update a product that has variants, I receive the following generic error:

"userErrors" => array:1 [
        0 => array:3 [
          "code" => "GENERIC_ERROR"
          "field" => array:1 [
            0 => "input"
          ]
          "message" => "Something went wrong, please try again."
        ]
      ]

This error doesn’t provide much detail, making it difficult to troubleshoot. What’s even more confusing is that the same implementation works fine in another Shopify store but fails in this particular store.

Has anyone faced a similar issue or have any insights on what might be causing this? Any help would be greatly appreciated!

Thanks!

Hey Kriti,

A couple things to look out for here:

  1. Metafield Type and Owner: Ensure that the metafield type is correctly set to boolean and that the ownerId corresponds to the product or product variant. If the metafield is intended for the product level, ensure that the ownerId is the product’s ID. If it’s for a variant, the ownerId should be the variant’s ID.
  2. Synchronous vs. Asynchronous Mode: The productSet mutation has different behaviors in synchronous and asynchronous modes. If you are updating products with many variants, consider using asynchronous mode to avoid input limits or processing issues.
  3. Metafield Definition: Verify that the metafield definition exists and is correctly configured for the product or variant. If the metafield definition is missing or misconfigured, it could cause errors. You can use the metafieldDefinitionUpdate mutation to update or correct the metafield definition.
  4. Error Debugging: The generic error message you are receiving makes it difficult to pinpoint the issue. To debug further:
  • Use the productOperation query to check the status and errors of the asynchronous operation if you are using asynchronous mode.
  • Ensure that you are capturing and reviewing all userErrors returned by the mutation to identify specific issues.
  1. Store-Specific Configuration: Since the implementation works in another store, compare the metafield definitions, product configurations, and permissions between the two stores. Differences in metafield definitions or access scopes might be causing the issue.
