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

```python
system.perspective.print(event)

```

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

```python
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:

I thought I had encountered this bug in 8.3.3, see this other thread for my notes on it.

> As an update, I worked with @cmallonee , niether of us could replicate this issue. I originally had the issue from the context of the designer interface and was connected to the gateway via VPN and there may have been a substantial amount of latency between the session and the gateway.
