Output Content Type	application/json

The json-patch transformer applies the provided patch to the data message payload. The patch must be a valid RFC 6902 JSON patch document. Supported operations include:

• add
• remove
• replace
• copy
• move
• test

Patches that specify a remove operation on non-existent fields will be applied successfully with the remove operation ignored. Patches that specify an add operation on a non-existent nested field will have the nested object structure automatically injected into the payload.
