Are you sure it's getting triggered twice?
I added a print statement to the onFileReceived event and it only fired once when I uploaded a file

system.perspective.print(event)

I ran into that issue myself a while back, and came up with this workaround:

def runAction(self, event):
	import java.lang.Exception
	from threading import Timer
	
	# Fixes a bug in Ignition that causes this event to fire twice in a row...
	def setOkayToUpload(self):
		self.custom.okayToUpload = True
	
	if self.custom.okayToUpload:
		self.custom.okayToUpload = False
		...(process upload)...
		Timer(0.5, setOkayToUpload, [self]).start()

There was a bug where small files would trigger twice when uploaded.

I used this work around as I am not quite ready to update:

[IGN-8219] Perspective File Upload onFileReceived being called twice

I easily get around it by modifying the code to check the filename to ensure we don't do the same file twice in a row: def runAction(self, event): # Grab the file name and data filename = event.file.name filedata = event.file.getString() # Check if this file has just been uploaded - to stop a double import (potential platform/browser bug) if filename <> self.custom.filename: # Call the import function on the table self.parent.parent.getChild("Table").importCSV(filename, filedata) …
