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

```json
{"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:

1. imported your flow through the import dialog.
2. deleted all the OPC nodes (I wasnt about to install that!)
3. tried to deploy - it would not.
4. with devtools opened, operated the deploy button once more & debugger stopped on the line highlighted in the screenshot above
