Why Serilog PostgreSQL sink is not working through Configuration?

I have tried PostgreSQL sink for Serilog through code and it works like a charm.
Here is working code:

    static void Main(string[] args)
    {
        var connectionString = "Server=localhost; Port=5432; Database=subscriptions_log; User Id=postgres;Password=postgres";
        string tableName = "errorlog";

        IDictionary<string, ColumnWriterBase> columnWriters = new Dictionary<string, ColumnWriterBase>
        {
            {"message", new RenderedMessageColumnWriter(NpgsqlDbType.Text) },
            {"level", new LevelColumnWriter(true, NpgsqlDbType.Varchar) },
            {"raise_date", new TimestampColumnWriter(NpgsqlDbType.Timestamp) },
            {"exception", new ExceptionColumnWriter(NpgsqlDbType.Text) }
        };

        using var log = new LoggerConfiguration()
            .WriteTo.Console()
            .WriteTo.PostgreSQL(connectionString, tableName, columnWriters)
            .CreateLogger();

        log.Information("Hello, Serilog!");
    }

But when I use it through configuration file serlig creates table in the database but does not insert any rows because of "Npgsql.NpgsqlBinaryImporter.Complete()" not found.
"Here is detailed error:

Exception while emitting periodic batch from Serilog.Sinks.PostgreSQL.PostgreSQLSink:
        System.MissingMethodException:
        Method not found: 'Void Npgsql.NpgsqlBinaryImporter.Complete()'.

Config File

        {
        "Serilog": {
            "Using": [ "Serilog.Sinks.PostgreSQL.Configuration" ],
            "MinimumLevel": "Debug",
            "Enrich": [ "WithMachineName" ],
            "WriteTo": [
                {
                    "Name": "PostgreSQL",

                        "connectionString": "LogsDb",
                        "tableName": "errorlogs",
                        "needAutoCreateTable": true
                    }
                }
            ]
        },
        "ConnectionStrings": {

            "level": {
                "Name": "LevelColumnWriter",
                "Args": {
                    "renderAsText": true,
                    "dbType": "Varchar"
                }
            },
            "raise_date": "TimestampColumnWriter",
            "exception": "ExceptionColumnWriter"
        }
    }

And the Calling Method:

    static void Main(string[] args)
    {
        Serilog.Debugging.SelfLog.Enable(msg => Debug.WriteLine(msg));
        Serilog.Debugging.SelfLog.Enable(Console.Error);

        IConfiguration configuration = new ConfigurationBuilder()
            .SetBasePath(Path.GetFullPath(Path.Combine(Directory.GetCurrentDirectory(), "..", "..", "..")))
            .AddJsonFile("serilog.json", optional: false, reloadOnChange: true)
            .AddEnvironmentVariables()
            .AddCommandLine(args)
            .Build();

        using var log = new LoggerConfiguration()
            .ReadFrom.Configuration(configuration)
            .CreateLogger();

        log.Error("Hello, Serilog!");
    }

Configuration file is exactly as described here. For test purpose I tried with .net 5.0 and 3.1 with out success.
Unfortunately I can't use it through code as I am using a 3rd party library that uses serilog for logging to sql server and I have to switch to PostgrSQL only through configuration. Any help?
