The below occurs on NR start, when passing in a null payload but with msg.ui\_control set.
Meant to add:
NR v1.0.4
Dashboard v2.19.4
ui\_table v0.3.0
```auto
TypeError: Cannot read property 'config' of null

Thank you for the info. There might be an issue.
Please try to pass msg.ui\_control either without a payload at all or a valid payload (array or object with a command structure). As `null`is an object there is a check missing, sorry
Chris

Not exactly sure what is occurring. I have removed msg.ui\_control from the equation. Array is now being sent through to the table on initialisation. However the error remains.
Anyhow, easy fix at the moment is to not restart NR.

Can you share the flow?

Sure, but I will need to trim it first.

Strange days. I deleted the ui\_table node, then re-instantiated it and deployed. Error is now gone.

That to hear. I looked into the code and a test for `msg.payload===null` is indeed missing but should not cause the problems you described.
