Simple Open AND and Close Flow

This is for Open and Close Gate

and here are the debug errors I'm receiving

Your post does not say what node.
Please post a simple flow showing issue, so we can see what is occurring.
How to import/export a flow

I have edited the topic category as this is not about developing a node.

Pure guessing: msg.payload isn't an object, but coming in e.g. as string.

Well it certainly won't work if you inject a timestamp into the change node, as msg.payload.status will not exist.

Here it is working.

Can you see the issue of posting an image?
