Expression nodes aren't loading in

Hi,

My colleague has a workflow containing multiple expression nodes. When I load this workflow into my local space, it returns an error when loading in the nodes.

I am using knime 5.3.2 and my colleague is using 5.4. I don’t understand how this could affect reading in nodes that are available on both versions?

Any ideas anyone has would be muchly appreciated.

Thanks in advance,

Matt
