You may run into an instance when calling a Sila end point that looks like the below.

This error usually means that you are passing the wrong user_handle parameter in the Authorization Header. This can happen when you are trying to work with multiple users i.e. individuals and businesses and inadvertently are passing the wrong user_handle parameter in the Authorization headers.

In Postman, you can click on the "Auth" tab and verify that you are passing the correct user_handle for your API call
