Schema Error: Product descriptions must be between 1 and 5000 characters.

Product descriptions are an important part of Shopping ads, helping potential customers to get more details on what you are selling as well as helping Google match your products to relevant searches. You must have a description to produce a Google Shopping ad. However, Google limits product descriptions to 5000 characters. In order to avoid having your product descriptions being cut off in the middle of a sentence, you should make sure that your product descriptions are less than 5000 characters.

Changing your product description usually involves editing the product descriptions on your website.
