I have a subroutine (that I call with a `link call` node) which doesn't have a `link out` node (i.e. "SendToTelegram"). How can I avoid the timeout of the` link call` node?

if you're not expecting a return for your `link call` just use a `link out` and `in` only without a `link-call`. A `link call` expects a return

Ad for those times when a naughty node swallows the reply (resulting in a timeout) you can `catch` the timeout error and act accordingly.

@Steve-Mcl I noticed that a subroutine cannot be part of a subflow. I am getting the error: `Missing return node information`

A link call **can** call out of a subflow to an external subroutine but it makes no sense to call into a subroutine.

Think for a second what a subflow does: it generates `n` copies of its self - so which link-in would a link-call call to?

Additionally, link-call does work internally in a subflow when calling a link-in that exists in the same subflow.

Got it. Thanks
