GetCategoryCommand not working SXC 9.2

Question

I am working on SXC 9.2 and writing custom plugin. I need to pick Category information so I have written the below code to get the category information.

public class CustomCategoryCommand : CommerceCommand
    {
        private GetCategoryCommand _getCategoryCommand;

        public async Task<Category> Process(CommerceContext commerceContext, string categoryID)
        {
            //Category category = null;

            Category category = await this._getCategoryCommand.Process(commerceContext, categoryID);

            return category;
        }

        public CustomCategoryCommand(
                GetCategoryCommand getCategoryCommand
            )
        {
            this._getCategoryCommand = getCategoryCommand;
        }
    }

It is always returning null. While debugging I could not find any exception. It is simply returning null.

Parameter- CategoryId: Entity-Category-Habitat_Master-Departments (Existing habitat categoryId)

Please, can somebody indicate what mistake am I doing here !!!!

Thanks.

Answer 1

It usually happens when you call your custom api from postman and forget to add some required headers:

Content-Type:application/json
ShopName:{{ShopName}}
ShopperId:{{ShopperId}}
Language:{{Language}}
Currency:{{Currency}}
Environment:{{Environment}}
GeoLocation:{{GeoLocation}}
CustomerId:{{CustomerId}}
Authorization:{{SitecoreIdToken}}

If Environment header was not passed to request, by default, XC resolves Environment as a Global Environment. In your case, you need to pass HabitatAuthoring environment.

Add them to your postman request headers and execute your request.

It should work now.
