Hello,

I am noticing the following error message coming from my network extension on the system logs (<networkextension> is a placeholder I put in place of the ID of the network extension):

Code Block error	12:50:11.528868+0200	<networkextension>	Could not find app info, return the original flow without filling in app info

Q: Is this indicative of an issue with the network extension?

These messages are also present consistently just before the error message (<process> is a placeholder that I put in place of the process name):

Code Block default	12:50:11.515038+0200	nehelper	UUID cache generation changed from 383933 to 383934
default	12:50:11.523397+0200	nehelper	Failed to find <process> using neagent
default	12:50:11.523015+0200	neagent	Failed to find <process> in LaunchServices
default	12:50:11.527575+0200	nehelper	Setting UUID cache generation to 383935

I believe these info messages might be related as they are coming from nehelper and neagent and they are consistently present with the error message.

Thanks in advance for your help!
Cheers,
Arianna

Hello Arianna,

Q: Is this indicative of an issue with the network extension?

This look like neagent could not find the process information for the process the flow is originating from. I would not worry about this as this can happen and it is good to have a default case for handling flows like this when your extension cannot determine the process info.
