I have this subroutine which I am calling with a link call node: [Screenshot 2024-01-04 alle 16.10.24] I am always getting "Missing return node information", due to the split function, which contains: msg.payload.split("##").forEach(e => { if (!e) {return;} node.send({ payload: e + "##"}) }); Any way to let it work?

Try this then. you will need to remove the "fake data" node and check that the output of the EXEC maintains the msg.linksource property for it to work in production.
