Using Apache Calcite on Windows and trying to query the DEPTS.csv used on the website tutorial I get a NullPointerException when using Calcite Core 1.13.0 but when I use 1.12.0 the issue disappears.

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));
    }
And the exception is as follows:-

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