So your flow does indeed trip up the client side code.
I am running with non minimised client code, the error occurs here...
I am certain this can be contained in code but - how to handle this situation - is a completely different question.
This ui_group in your flow has a z index that doesn't exist in the flow
{"id":"53e6c4b8.1b0f7c","type":"ui_group","z":"dfe4ec36.0a5a5","name":"Default","tab":"","order":1,"disp":true,"width":"6"},
I think it might be worth tagging Nick (@knolleary) to have a look see what he makes of this.
INFO: tab is null after returning from RED.nodes.subflow() causing undefined error when accessing name property.
STEPS I TOOK:
- imported your flow through the import dialog.
- deleted all the OPC nodes (I wasnt about to install that!)
- tried to deploy - it would not.
- with devtools opened, operated the deploy button once more & debugger stopped on the line highlighted in the screenshot above
