Output
The output of this node is structured as an array of JSON objects, each representing the result of the operation performed on the specified post meta fields. If the operation is successful, each object will contain details about the created or updated meta entry, including its ID and value. If binary data is involved, it would typically represent file attachments or similar content, but this node primarily focuses on JSON outputs.
