Keys for TenantId and ClientId are mixed up

The keys for TenantId and ClientId are swapped in appsettings.json for the ToDoListAPI. See also text in section "Configure the service app (ciam-msal-dotnet-api) in https://learn.microsoft.com/en-us/samples/azure-samples/ms-identity-ciam-javascript-tutorial/ms-identity-ciam-javascript-tutorial-2-call-api-angular/#setup-the-sample.

Application worked as expected for me after swapping the keys.

from appsettings.json
"AzureAd": {
"Instance": "https://Enter_the_Tenant_Subdomain_Here.ciamlogin.com/",
"TenantId": "Enter_the_Application_Id_Here", //this needs the tenant id and not the application/clientId and vice versa
"ClientId": "Enter_the_Tenant_Id_Here",
"Scopes": {
"Read": ["ToDoList.Read", "ToDoList.ReadWrite"],
"Write": ["ToDoList.ReadWrite"]
},
......
}
