Exception error creating csv file

[Smee]

Can someone see a problem with this code?

I get an exception error thrown when trying to create the csv file
java.lang.NullPointerException

Cursor1=SQL.ExecQuery("Select * From Customers")
For i = 0 To Cursor1.RowCount - 1
    Cursor1.Position = i
    cols = Array As String(Cursor1.GetString2(0),Cursor1.GetString2(1),Cursor1.GetString2(2),Cursor1.GetString2(3),Cursor1.GetString2(4))
    list1.Add(cols)
Next

su.SaveCSV(File.DirRootExternal, "customers.csv", ",", list1)
Cursor1.Close

It seems there is a problem with the last field. if i drop the last field it works ok so it is something within my text

I thought it was a similar problem...
But I have commented any action in the between!
I do not understand why the Load function find the file, while the Save not!
It should be in "File.DirAssets"?
Thank you for your help...

      'Load saved Parameters
   'It contains the name of the others files and the selected parameters
   List0.Initialize
   
   Try
      List0 = strUt.LoadCSV(File.DirAssets, "config.ini", colon)
   Catch
      ToastMessageShow("Error: "&LastException.Message, True)
   End Try

   'Changes the modified value
   indL = List0.Size
   'For indI = 0 To indL-1
   '   ReadRow0 = List0.Get(indI)
   '   If ReadRow0(1) = strSelectedTable Then
   '      ReadRow0(2) = rc.Row
   '      List0.Set((indI), ReadRow0)
   '   End If
   'Next

   'Writes new value
   Try
      strUt.SaveCSV(File.DirAssets, "config.ini", colon, List0)
   Catch
      ToastMessageShow("Error: "&LastException.Message, True)
   End Try

You cannot save to File.DirAssets. It is a read only folder.

Thank you very much...
I haven't seen it, and the message "file not found" did not help .
