halt. This node can be used to catch those errors and handle them with a
dedicated flow.</p>
<p>The node will catch errors thrown by any node on the same tab. If there
are multiple catch nodes on a tab, they will all get triggered.</p>
<p>By default, the node will catch errors thrown by any node on the same tab. Alternatively
it can be targetted at specific nodes.</p>
