I get an "

```auto
ExpressionError: Invalid expression

```

" Error even though the nodes are connected and everything seems working for me.

## What is the error message (if any)?

hello @Jakob_Feinbock

It seems you have more than one item in the input. And some of the items don’t have a path back to that node.

Consider simplifying the workflow with sub workflows
