Google Apps Script doesn't find file

Question

I just want to check, if a file already exists on my Google Drive:

var Filename = 'xyz';
var Files = DriveApp.getFilesByName(Filename);
if (Files.hasNext()) { ... }

This did work very good for some month. But suddenly it stopped working a few weeks ago. Now the result of hasNext() is always false - although the filename definitely does exist.

Did anything change at Google Apps Script? Is anything wrong with my code? Can I fix it?

Answer 1

Finally, I found how to retrieve files with filename included umlauts. Please confirm this. title contains was required as a query. It was not title= . Please confirm the following script for your script.

Script :

var name = "Übergabe News";
var Files = DriveApp.searchFiles('title contains "' + name + '" and trashed=false');
if (Files.hasNext()) { ... }

Also you can use this for "20170817 Nachrichten-Übergabe" in your comments. I'm sorry for being late solution.
