null in the notification area

[GeorgeCastanza]

Hi there,

I'm using your Boolean Ultimate Logic node (a lot). it's been great. Recently I added a created a new flow, and I'm getting lots of null's in the notification area. I'm unsure as to why. I know they have received the right amount of payloads (3 if expecting 3).

I have two flows that receive the same (but reversed) payloads, one is showing as it should, the second is showing nulls.

Hello George I need to view, what are you passing to the boolean Logic node. Can you please paste here the code of your flow? Not all flow, you can paste only the affected portion.

Hello ther's an issue in inporting the code. Cannot paste it into my flows because of a json error. Can you try to zip the exported flow and then attach it here?

Sorry, I put this in the code quotes. And imported back into NodeRed, and it worked. Thanks for your help on this. Compared to yesterday, the other Boolean Ulitmate is showing null, so something is amiss, unless there is a change, but I checked the changelog.

[Supergiovane]

Hi If global.get("lux_out") doesn't return "dark" or "bright", you'll sent a message with undefined payload to the boolean logic. I suspect that boolean logic node, receives a message input before global.get("lux_out") has been set. Please replace the first two functions with this:

[GeorgeCastanza]

Thanks for bearing with me. However, the global variable has been set for many months. It's either, dark or light. Never anything else. Anyway, I tried your suggested code, and it's still showing the error. Note: the error is not with the output of the Node, only the text shown under the Node itself in light gray.

Notice how the null is now in the bottom node, whereas in my post above (post 1), it was the top node. The null should be showing "false".

[Supergiovane]

Hello, yes i saw this. null null null, means that the node is not outputting any message, because all 3 input topics are false. You set the boolean logic to output only "true" values. That's normal. "Null" means "no values are sent". In the next version, i'll replace "null" with something more meaningfull.

[GeorgeCastanza]

Ahh, Ok. Then there is no error. My apologies.

[GeorgeCastanza]

Are you able to update the docs for future people. Great node by the way!
