Describe the bug

Calling pricing.GetProducts() returns a different type beginning in v1.44.46, breaking existing programs. The PriceList field in pricing.GetProductsOutput is a *string, where it was previously an aws.JSONValue, which is a map[string]interface{}. Clients relying on the previous type are broken by this change:

products, _ := pricing.GetProducts(input)
b, _ := json.Marshal(products.PriceList)
fmt.Println(string(b)

Where previously this would print a JSON array where each element is an object, it now prints a JSON array where each element is a string (a stringified JSON object).

Expected Behavior

Either behavior is acceptable, but I would expect the type signature for all functions to remain the same across all revisions within a major version.

Current Behavior

Currently, an array of strings is returned

Reproduction Steps

For any pricing query (input)

products, _ := pricing.GetProducts(input)
b, _ := json.Marshal(products.PriceList)
fmt.Println(string(b))

This prints an array of strings

Possible Solution

No response
