Script fails on time-driven trigger?

[Marco Nieuwenhuis]

Hi Experts,

I have a script to convert Excel file to Google Spreadsheet. When I execute the script from within the script editor it works perfectly fine but when I set a time-driven trigger it fails over and over with the error below.

The following object could not be retrieved: the iterator has reached the end. at convertExceltoGoogleSpreadsheet (Excel_Convert: 4)

Does this have something to do with rights perhaps? Below the script I'm using. 

Hope someone can help me out on this. Thanks in advance!

Regards,

Marco

var dstFileId = '1PUXjW0fxR66...........'; // file Id of Existing Spreadsheet

function convertExceltoGoogleSpreadsheet(fileName) {

fileName = fileName || "test_ds.xlsx"; //  excel_file_name.xlsx = name of specific Excel file

var excelFile = DriveApp.getFilesByName(fileName).next();

var fileId = excelFile.getId();

var srcFileId = fileId; // file Id of Excel file

Drive.Files.update({}, dstFileId, DriveApp.getFileById(srcFileId))};

I think that the error message indicates that the file with "fileName" is not found. How about confirming the filename sent to "convertExceltoGoogleSpreadsheet(fileName)" again?
