Error message

product_attributes.gtins_01: the format is not valid, int format is expected

What does this error mean?

The "gtins_01" field received a non-numeric value instead of the required numeric integer format ("EAN"/"UPC").

How to solve it

To resolve this issue, you must ensure that your GTINs contain only numbers. Follow these steps:

1. Identify the affected products: Locate the products in your catalog that have non-numeric characters (such as letters or symbols) in the "gtins_01" attribute.

2. Correct the values: Update the "gtins_01" attribute for these products so that they contain only a valid, numeric GTIN.

3. Resynchronize your feed: Trigger a manual product synchronization to send the corrected data to the marketplace.
