Button "Badly formatted buffer"

Dashboard
1

Hallo.
I'm new here as you will recognise by my question.
In my project a slider value shall be confirmed by pushing a button before it is sent to the PLC.

First of all: It works!

But using a debug node an error message occurs. Why? And why is the function not compromised by that error?

Adjustment in the button node

Thanks for making me a bit less stupid.

Which node is generating that error? Click on the node id above the error (9149....) and it will highlight the node. Then add a debug node showing what is going into that node to see what you are feeding it.

It's a button node. As you can see I feed a number and I get that number out, ok so far. Plus an error message that causes no trouble. But why? I could leave debug mode and forget it, but want to know, whats wrong with it.

Can you select that node and Export and paste it here please so we can see how it is configured. Also set Debug 1 to output the full message and show us what is there.

I can't see how that button node can be passing a numeric payload to the debug node, though it does give me a "badly formatted buffer" error.

Can you export those 5 nodes and paste them here (use the </> preformatted text button so the forum does not break the code)?

The help text says that it sends whatever is configured in the node. It should not send the incoming payload. That suggests that the node is mis-configured.
