In order to rectify the error message could you ensure the following:
All of your products are in valid Shipping Profiles. If you have no General Profile rates and you add a product, you'll need to move it to a valid profile as soon as the product is created, otherwise no rates will be provided.
If you've added a new Location, it may not have been added to your shipping rates. Please check your location, shipping profile, and the inventory of the product/variants for how they are configured.
Ensure the location that stocks the product has a shipping rate assigned in the shipping profile where the product is listed.
Ensure the country of the shipping address is an active market under Settings > Markets.
Check the product has both physical + requires shipping, and has proper weight assigned.
