Solution
Once your application is registered in your Operator Cockpit, the following two variables are added to the environment variables for all components of your App:
MDSP_KEY_STORE_CLIENT_ID: "clientID"
MDSP_KEY_STORE_CLIENT_SECRET: "ClientSecret"
When testing your code on the Developer Plan Tenant, we recommend adding those two environment variables using the credentials for your Dev Tenant. This way, you will create the same behavior as the one you will find on the productive system.
