The tool works nice when the Unique ID field is a field of the table. It fails when the option merge - all is activated. Nothing is added to the map canvas.
I tried with different shapefiles but nothing changes. In attach you can find a sample file.
This is the error in the log:

An error has occured while executing Python code:
