An error occurred while writing to logger(s). (Input string was not in a correct format.)

I'm using nlog with .netcore REST Api as:

using Microsoft.Extensions.Logging;

 }
 catch (Exception ex)
 {
   Logger.LogCritical(-1, ex, string.Format("error occurred: {0}", ex.Message));
 }

But getting error as:

An error occurred while writing to logger(s). (Input string was not in a correct format.) (Invalid format string. Expected 4 format parameters, but failed to lookup parameter index 1)

And in Program.cs:

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args).
            ConfigureAppConfiguration(config =>
            {
                config
                .AddJsonFile("appsettings.json", false, true);
            })
            .UseNLog()
