I tested the easy example https://developers.google.com/apps-script/class_fileupload?hl=es to upload file using apps script.
I used two different spreadsheet but the error is the same. I cut and paste the example. doGet seems run ok, but when submit button is pressed the error message "An unexpected error occurred" appear.
Well, I discovered the problem is..... the url call: The publish system says now you use this format: https://docs.google.com/macros/s/[ID service]/exec But if you change by the old format http://docs.google.com/macros/exec?service=[ID service] doGet and doPost work well.
I don't know what's happend. Why the new apps script publishing system appear with a format that seems it doesn't work well (https://docs.google.com/macros/s/[ID service]/exec).
May be, it is an issue.
Thanks in advance.
