Hi Pol,
Thanks for getting in touch with us.
You are getting that error for the offer field.
It looks like you have added an offer but haven’t added the price yet. Please add that to get rid of the issue.
Here’s a screenshot for reference:

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Hi, thank you for your quick answer, there isn’t any offers on those products highlighted by google console. All the products highlighted are variable.
I’ve done a bit more of investigation, and it looks like:
– I’ve added “$entity[‘offers’][‘priceValidUntil’] = ‘2050-01-01’;” to get rid of that warning.
– This works fine for simple products where there is only 1 offer.
– In variable products it sets the ‘priceValidUntil’ for the ‘offers’ instead to each individual ‘offer’.
– I’ve temporarily added a check if the product is simple to add that ‘priveValidUntil’ (function below)
– I’ve looked at your schema generating code and you create an array for all the variations but I didn’t seem to be able to access it with $entity[‘offers’][‘offer][‘priceValidUntil’], would you be able to help here?
Kindest Regards
Pol

Hello,
Thank you for contacting Rank Math today.
Could you please test the following snippet for variable products:
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
global $product;
if ( $product->is_type( 'variable' ) ) {
$variations = $product->get_available_variations();
foreach ( $variations as $key => $variation ) {
$entity['offers'][ $key ]['priceValidUntil'] = '2050-01-01';
}
} else {
$entity['offers']['priceValidUntil'] = '2050-01-01';
}
return $entity;
});
Looking forward to helping you. Thank you.
