Aspire.Hosting.Azure.AppService : AddAzureAppServiceEnvironment throws System.InvalidOperationException: "The endpoint `https` is not allocated for the resource"

[raddragan]

Is there an existing issue for this?

Describe the bug

Running aspire publish --debug with builder.AddAzureAppServiceEnvironment() throws the above exception.

The ApiService must run locally with an https endpoint for many reasons.
The ApiService requires launchSettings.json to be defined, or one will be generated by default.

There doesn't appear a way to override the endpoint definitions when publishing aspire to circumvent this error.
It appears that the launchSettings.json are consulted.

Expected Behavior

I have read Azure App Service constraints where it says:

Single endpoint: App Service supports only a single target port. Resources with multiple external endpoints with different target ports are not supported. The default target port is 8000, which can be overridden using the WithHttpEndpoint extension method.

This is fine, so I expect a way to override and to define this single endpoint.

Steps To Reproduce

Directory.Packages.props:

<PackageVersion Include="Aspire.Hosting.Azure.AppService" Version="13.0.2-preview.1.25603.5" />

Aspire.AppHost/AppHost.cs:

builder.AddAzureAppServiceEnvironment("appServiceEnvironment");
...
var apiService = builder.AddProject<Projects.ApiService>("apiService")
    .WithHttpHealthCheck("/health")
    .WithExternalHttpEndpoints()
    .PublishAsAzureAppServiceWebsite((_, _) => { });

ApiService/Properties/launchSettings.json:

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "profiles": {
    "https": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": false,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:44444",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}
