1 Deprecated: Message properties overriding set node properties
anna2130 edited this page 2014-11-03 05:31:19 -08:00

Properties can be set in a node or in an incoming message to define behaviour.

For example, when using a file node, either setting 'Filename' in the node or setting msg.filename in an incoming message will read from that file. If both properties are set msg.filename will currently override the node property.

This behaviour is only found in some nodes and can have unexpected consequences as described in this issue. Therefore, message overriding has been deprecated.

In future nodes and future releases msg.some_property will only be used if the property is not set in the node.

Nodes currently using the override functionality will continue to function in this release but will also receive a warning noting that this behaviour is deprecated.

The core nodes and properties affected by this behaviour are:

  • http request: msg.url and msg.method
  • email: msg.to
  • file: msg.filename
