Validation Warning: Product does not exist.

There is an error with the product in Mirakl which means an offer cannot be completed.

This error can happen on a product with variants and without variants.

If you see it on a product variations the error may only apply to some of the variants but not others.

Therefore some variants may be listed, some may not due to this error.
The advice below only applies to standalone non-variant type products.

The product is not available to create an offer within Catch/Mirakl. Either it needs approval by Catch, or has been specifically not-approved for a specific reason.

This means that the product can be either:

Pending approval - the Catch curation team will approve/reject the product within 5 business days from when it was submitted


Rejected - the curation team rejected the product. Sellers can review their rejected listing report via their Catch Partner Portal :

The rejected listing report in Catch will specify more succinct and actual errors that apply to that SKU.

If after this timeframe (5 business days) the product is not live and not available on the rejected report, the seller should contact the Seller Support team via and provide the relevant SKU, identifier (UPC, EAN or MPN), and product name so they can investigate why the offer is not live.

If you can see this error on a product with Variations please also check the rejected report and Catch and also consider information in this FAQ here.

Catch Image Validation Errors

Catch Marketplace has specific image requirements and if not applied this will lead to products not listing.

We recommend following this FAQ in the Catch Portal to find the specific Image Error.

NOTICE6 | Variant ID already exists in our system with a different variant product data

This message on the product page in Omnivore is a warning message. The product is most likely listed but has warnings from Catch Marketplace.

The warning message will appear when we upload a product to an existing listings on Catch. The existing listing on Catch is mostly likely owned by another seller on Catch and your variant structure does not match the existing variant structure that Catch has. We can create an offer against the existing product on Catch, hence it is listings, but we cannot update the data because the data is owned by another seller.

Catch validation error 2006|The attribute 'gender' (Gender) is not in the possible values set in the value list.

You  may see this error for other attributes that are not gender. This is a generic error type if Catch sees something not on its values list.  

This error may occur if you have a variant type called 'Gender' and Catch is not accepting that variant type. By default Catch accept size and colour.

Our suggestion is to read this FAQ, specifically the heading Marketplace Attribute Mapping.

This is the 6th section in the article. Please have a read and as explained reach out to us so we can apply the necessary data for you.

Once we add that variant attribute data into Omnivore Catch will be able to see Gender in the feed.

NOTICE 2 | Variant product already exists in our system with a different structure. Please contact support

This error means that the product may have been listed with a size or colour variant or just a colour variant, and then a variant type has been added or removed to the product in your eCommerce Store so Catch detect a variant structure change which they cannot handle.
