Actually not, I'd like to catch warnings to use them in another flow/node, the question you quote is asking for a removal/disabling of such warning messages.

It's very similar to this one:

> I love using the "catch" node to catch all errors from a flow and then pipe them to any notification system like Telegram, Email, etc. Is there anything similar that works with node.warn()? How could I catch .warn() messages and send them on to some notification system?
