I am running my application as I have been for the past YEAR. today, db2 decided to give me this error:

I am running my login function, which the query looks like this:

    var userLogin = "select * from login where USERNAME = ?";
  ibmdb.open(ibmdbconnMaster, function (err, conn) {
    if (err) return console.log(err);
    conn.query(userLogin, [inputUsername], function (err, rows) {
      if (err) {
        console.log(err);
      }

any chance anyone can help?
