Hello, I am experiencing an issue when trying to upload some Product Items to the Product Catalog via the API. Although the creation of Product Items completes without errors, the items do not appear in the Product Catalog. When searching by retailer_id (Content ID in Commerce Manager), no results are found.

Through experimentation, I've discovered that modifying certain fields, such as brand or description, sometimes allows the Product Item to be successfully loaded into the Product Catalog. However, there appears to be no consistent pattern in what needs to be changed in the source data.

As a result, I am unable to create a Product Set with these Product Items. The error message received during Product Set creation is: "We disallow the creation of empty product sets. Please add products to your catalog and create a set that contains at least one product."

I would appreciate any assistance or advice you can provide.

I am using the facebook-java-business-sdk version 19.0.3.

Thank you.
