Use a shipping dimension value within the limits
Why this issue is happening
The shipping height [shipping_height] attribute is an optional attribute that allows you to specify dimensions for carrier-calculated shipping rates in the Merchant Center. This issue occurs when the dimension value that you’ve submitted for shipping height [shipping_height] is higher than Merchant Center permits.
How to fix your issue
To correct this issue, submit a dimension value within the specified limits. The limits for shipping height [shipping_height] are 1 cm - 400 cm and 1 inch - 150 inches. Your shipping costs are calculated based on dimensions and weight, so providing accurate dimensions within the limits helps ensure that Google calculates these costs correctly.
