Could not execute because the application was not found or a compatible .NET SDK is not installed.

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 'RCM.Gateway.HttpApi.Host.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

I was trying to run the API container, i was getting the issue.....

The error came as my COPY command in 2nd stage build was configured wrong
