在 Windows 上使用 Apache Calcite 并尝试查询网站教程中使用的 DEPTS.csv 在使用 Calcite Core 1.13.0 时出现 NullPointerException，但是当我使用 1.12.0 时问题消失了。

Properties info = new Properties();
    info.put("model",  "../src/test/resources/files.json");
    info.setProperty("lex", "JAVA");

    Connection connection = DriverManager.getConnection("jdbc:calcite:", info);
    Statement stmt = connection.createStatement();

    String sql = "select * from FILES.DEPTS"; 
    ResultSet rs = stmt.executeQuery(sql);
    while(rs.next()) {
        System.out.println(rs.getString(1));
    }

例外情况如下：-

java.sql.SQLException: Error while executing SQL "select * from FILES.DEPTS": null
