Error: "The API endpoint is incompatible with the product catalog version. You are calling product catalog 1.0 API endpoint but you are using product catalog 2.0"

• This error occurs because of migrating of sites from PC1.0 to PC2.0.

Please follow the below steps to identify the root cause

• Step 1 - Check if PC 2.0 is enabled for this site. Use the steps given here to find it.
• Step 2 - If you are in PC 2.0, it's probable that you are still using the PC1.0 API of Create Plan or List Plans and thus leading to the error or vice versa: you are in PC 1.0 but you are using APIs related to PC 2.0. You can refer to PC 2.0 API here.
