Update does not work with guid primary key in PostgreSQL

[yoyrandao]

I'm trying to perform Update method, but it fails with execution error:

Npgsql.PostgresException : 42883: operator does not exist: character varying = uuid
Data:
  Severity: ERROR
  InvariantSeverity: ERROR
  SqlState: 42883
  MessageText: operator does not exist: character varying = uuid
  Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
  Position: 104
  File: parse_oper.c
  Line: 647
  Routine: op_error

Model:

public record Account : Entity
{
      public string? Name { get; init; }

      public string? TokenHash { get; set; }

      public string? CertificateThumbprint { get; init; }

      public Guid[]? RoleIds { get; init; }
}

public record Entity
{
      public Guid Id { get; set; }
}

Mapping:

internal sealed class AccountMapper : ClassMapper<Account>
{
    public AccountMapper()
    {
        Table("account");

        Map(x => x.Id).Column(nameof(Account.Id).ToLower()).Type(DbType.Guid).Key(KeyType.Guid);

        Map(x => x.Name).Column(nameof(Account.Name).ToLower()).Type(DbType.String);
        Map(x => x.TokenHash).Column(nameof(Account.TokenHash).ToLower()).Type(DbType.String);
        Map(x => x.CertificateThumbprint).Column(nameof(Account.CertificateThumbprint).ToLower()).Type(DbType.String);

        Map(x => x.RoleIds).Ignore();

        AutoMap();
    }
}

Update method:

public Account? Update(Account account)
{
    using var connection = _connectionFactory.Create(ConnectionString);

    connection.Open();
    connection.Update(account);

    return account;
}

And table:

CREATE TABLE public.account (
    id                    UUID  NOT NULL PRIMARY KEY,
    name              VARCHAR(255) NULL,
    tokenHash             VARCHAR(64)  NULL,
    certificateThumbprint VARCHAR(40)  NULL
);

Am i doing something wrong? Please help

Okay, i solved this with setting KeyType.Assigned instead of KeyType.Guid
