When uploading creatives in Google Ads, you may receive an error message. In most situations, the problem can be fixed by altering your file and re-saving. You can then try to upload your file again.
Check your ads using the Google Ads HTML5 validator.

Note: When you upload a new custom dynamic ad, make sure it has the appropriate type (dynamic) and business type. The business type of the creative should match the campaign, you can find more information about your feed at the Campaign Settings page. Custom dynamic ads can only be created in Google Web Designer.
Additionally, make sure that your ad is designed to show one product or more, but not a specific, fixed number of products (2 or 3, for example), because Google will only be able to guarantee that one or more products will be shown for dynamic remarketing.
