I am seeing this error:

```auto
Error: Invalid property expression: unexpected ' ' at position 7

```

This is the node (`change` node)

```auto
[{"id":"515a1c91.ae5a8c","type":"change","z":"bdc47459.27c378","name":"flow set Channel Passed","rules":[{"t":"set","p":"Channel Passed","pt":"flow","to":"payload","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":1530,"y":1020,"wires":[[]]}]

```

I am sending it values like: 134 105 and other numbers. So I don't get how it is _at position 7_ works.

I can post a bit more of the flow if you are interested. But I am not sure it will be of much importance.

(I'm stupid.)

The flow name: `Channel Passed`

Should be `Channel_Passed`

Fixed.
