Error: "The API endpoint is incompatible with the product catalog version. You are calling Legacy Product Catalog API endpoint but you are using Latest Product Catalog"

• This error occurs because of migrating of sites from Legacy Product Catalog to Latest Product Catalog.

Please follow the below steps to identify the root cause

• Step 1 - Check if Latest Product Catalog is enabled for this site. Use the steps given here to find it.
• Step 2 - If you are in Latest Product Catalog, it's probable that you are still using the Legacy Product Catalog API of Create Plan or List Plans and thus leading to the error or vice versa: you are in Legacy Product Catalog but you are using APIs related to Latest Product Catalog. You can refer to Latest Product Catalog API here.
