tried adding ENV, still got same error.

        env:
          - name: KUBERNETES_SERVICE_HOST
            value: 10.96.0.1

@Andy-Wu-2022 This should be fixed with release 0.1.3
Can you please confirm, so that I can close the issue?

[Andy-Wu-2022]

@cdavernas The previous error got fixed. Now it got a new error:

Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
  * You intended to execute a .NET program:
      The application 'Synapse.Server.dll' does not exist.
  * You intended to execute a .NET SDK command:
      It was not possible to find any installed .NET SDKs.
      Install a .NET SDK from:
        https://aka.ms/dotnet-download

[cdavernas]

I opened and am working on #92 to address the issue, which appeared on 0.1.3.

Closing this one as it has been resolved.
