I started to run into a Function Node Error in a Workflow. Losant Debug form shows the following message:

> {  
> “message”: “”,  
> “name”: “FunctionNodeError”  
> }

I tried to debug it, but the error goes away only if Function Node has no code in it.

The simple code like the following is also generating an error:

> var i = 1;  
> payload.debug\_i = i;

This is how workflow looks like:

Could you I get an advice what could be the reason for that?

@Alexander_Kondrov,

That’s a super funky error message, but we found what caused it. It has something to do with using `error` on the root of the payload along with the Function Node.

Our engineering team is looking into the root cause. But, for now, I would assume you have a payload path as `error` configured in the Validate Payload node. If you change that, all should work for now.

I’ll update once we have a fix found.

Hi Taron,

Thank you for the prompt replies as always. You were right, I used “error” name for an error path of Validate Payload node. I changed the name and din’t experience this issue anymore.
