connect MYSQL using FIREDAC

Question

I want to access MYSQL database using firedac DB access components and followed instructions from here CONNECT MYSQL WITH FIREDAC. I copy all connection parameters from Tmemo and try to execute MYSQLCon.Open procedure using this code below :

with MYSQLcon do
  begin
    Close;
    with Params do
    begin
      Clear;
      for i := 0 to mmo_connection_params.Lines.Count - 1 do
      begin
        Add(mmo_connection_params.Lines[i]);
      end;
    end;
    Open;
  end;

this code fails with error msg : can't write mariadb did not understand the error , how to fix it ?
