Hi, today my subflows stopped working without any reason.
This is the feedback from the console.
NodeRED 0.19.6 on AWS EC2 Ubuntu instance
TypeError: Cannot read property 'id' of undefined

Hi @albydnc - can you provide more information about your flows? THis doesn't give us much to go on - particularly as 0.19.6 is pretty old now.
Hi, I've updated to 0.20.5 and the error still remains. I can share the flows with you but they are pretty big.
On my other redundant AWS instance everything is working fine.

This is the console printout
Resolved. It was a link node that wasn't connected.
Well you are going to have to give us some clue as to what your flows are doing and how the subflows are configured. If you can't provide a summary, then please do send your flow file to me directly - nick.oleary@gmail.com
Ok - just seen your 'resolved' update. I'd like to know more specific details because this sort of error should not happen regardless of how the flows are configured.
What/where was the link node and what did you need to connect it to?
I've sent you the code via email. By the way, I think the error was caused by the deletion of a link node, which caused the other link node to point to an undefined node. This is not possible anymore, since in version 0.20.5 links are configured differently.
