I am doing a trailhead Apex Web Services: https://trailhead.salesforce.com/modules/apex_integration_services/units/apex_integration_webservices
When I follow the tutorial at the part Apex REST Walkthrough I created the class CaseManager logged into workbench and try to make a case with the URI /services/apexrest/Cases/ I get the error:
Service not found at: /services/apexrest/Cases/
Why is this? With The Rest API tutorial I had no Issues
namespace
enabled then add it in your request like this:/services/apexrest/your_namespace/Cases/
