Hi all,

How can I debug that kind of error which occurs visibly within a Split node ?

```auto
split TypeError: Cannot convert undefined or null to object

```

Thanks in advance

Hi.

I don't think you need to do what you ask.

I suspect the `message` going into the `split` node is a `null` message, or the part it is going to split isn't there.

On the output of the node before this put a `debug` node and set it to display **all** the message properties.

That may help you find the problem.

Hope that helps.

That's ok.

I know the feeling all too well.

Good luck.
