Google Merchant Datafeed magento 2 configurable product

I use wyomind to create datafeed for among other things Google merchant.

I keep getting error for configurable product that the price isn’t enabled.

When it is.

It’s for example a sweater, with sizes as simple products.

Buy I need the configurable product to show for example in Google shopping.

I update attributes for this configurable product.

Keeps saying that the price isn’t set up.

Also nothing to find about this issue online.

Someone can help please ?
