<p>Catch errors thrown by nodes on the same tab.</p>
|
|
<p>If a node throws a error whilst handling a message, the flow will typically
|
|
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>If an error is thrown within a subflow, the error will get handled by any
|
|
catch nodes within the subflow. If none exists, the error is propagated
|
|
up to the tab the subflow instance is on.</p>
|
|
<p>The message sent by this node will be the original message if the node that
|
|
threw the error provided it. The message will have an <code>error</code>
|
|
property with the following attributes:
|
|
<ul>
|
|
<li><code>message</code> : the error message</li>
|
|
<li><code>source.id</code> : the id of the node that threw the error</li>
|
|
<li><code>source.type</code> : the type of the node that threw the error</li>
|
|
</ul>
|
|
</p>
|
|
<p>If the message already had a <code>error</code> property, it is copied to <code>_error</code>.</p>
