output

Sets the destination property that receives the rewritten JSON tree.

This parameter applies to JSON Dotted Key Transformer (mmjsontransform).

Name:

output

Scope:

input

Type:

string

Default:

none

Required?:

yes

Introduced:

8.2410.0

Description

Defines where the transformed JSON object is stored on the message. The property must use a JSON-capable prefix ($!, $. or $/). When the configuration uses a leading $ symbol, it is stripped automatically before validation. The module rejects other prefixes during configuration.

At runtime mmjsontransform verifies that the destination property does not already exist. Attempting to overwrite an existing value raises an error and the action aborts without modifying the message.

Input usage

action(type="mmjsontransform" input="$!raw" output="$!normalized")
