in node.js, SQL command not properly ended at Error(native)

I'm using oracle in node.js, and I want to insert my sql query.

I tried to insert my query, but i can't insert.

This is my error:

Error: ORA-00933: SQL command not properly ended

This is my SQL query.

INSERT INTO test VALUES ('P0315','hey');

So, I tried it in sqlplus directly, and result is

1 row created.

Only in node.js, I find error. I use npm oracledb, and this is my insert code.

    var sql = "INSERT INTO test VALUES ('P0315','hey');";
    var doinsert1 = function (conn, cb) {
    console.log(sql);
    conn.execute(
        sql,
        function(err, result)
        {
            if (err) {
                return cb(err, conn);
            } else {
                console.log("Rows inserted: " + result.rowsAffected);  // 1
                return cb(null, conn);
            }
        });
};

can I ask why it doesn't work in only node.js? I'm sorry about my language skills, and Thank you for reading! :)
