@enr0c the error from my point of view does say that the URL/URI does not contain any value the node can work with. Maybe you can check how the path is being submitted and check if that would make any sense.
Question is what path format the text based file reader would expect, especially when run from the ‘perspective’ of the server - you can try and run the workflow on the server as a new job and see what the path is then.
Hello @enr0c, did you try to set the row delimiter of the <file reader> to custom with “\” as the delimiter? It worked at least for a very simple multi-line SQL file in my example. As far as I remember, you also use multiple comments that might make this even more difficult!?
