Avoid nlobjSearchResult has no public instance field or method named getAllColumns Error?

The error is usually encountered when the below code is being done:

var results = nlapiSearchRecord('issue', [savedsearchid]);
var sCols = results.getAllColumns();

To avoid the error, do this instead:

var results = nlapiSearchRecord('issue', [savedsearchid]);
var resultIdx = results[0];
var sCols = resultIdx.getAllColumns();
