Cloud-SQL: Failure to start container when deplying on gcloud

[faad021]

I am trying to try out this tutorial with cloud sql but I am getting error during deployment with the following message.

Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the
PORT environment variable. Logs for this revision might contain more information.
  X  Creating Revision... Cloud Run error: Container failed to start. Failed to start and then listen on the port defin
Logs

Here is the Program.cs file and the application already listens on the port. I do not know why I am getting this error

static class ProgramExtensions
    {
        // Google Cloud Run sets the PORT environment variable to tell this
        // process which port to listen to.
        public static IWebHostBuilder UsePortEnvironmentVariable(
            this IWebHostBuilder builder)
        {
            var port = Environment.GetEnvironmentVariable("PORT");

            var urls = string.IsNullOrWhiteSpace(port)
                ? "http://0.0.0.0:80;http://0.0.0.0:8080"
                : $"http://0.0.0.0:{port}";

            builder.UseUrls(urls);
            
            return builder;
        }
    }
