Wrong output format - Excel writer

Hello everyone,
I created a workflow where the Excel output is controlled by a variable that contains the path and the file name (directory path + file name).
In output I don’t find a working excel file, but an undefined format file (even if i configured the node as an xlsx output).
What can I do to resolve this problem?

Thank you in advance,

Here is an example!

@ARuggeri91 your path does not have an extension like .xlsx - so it might seem that the file is not valid.
