Hello, I'm looking to reference a specific artifact from the Phantom Playbook Visual Editor.
For example, a Phantom: Update Artifact block takes two parameters: artifact_id and cef_json. The list of default datapaths for artifact_id all follow the format of artifact:*.<field>, where the wildcard causes the update to occur on ALL artifacts. I would instead like to reference the first artifact in the container, so that only the first artifact is updated.
Is there a way to construct the datapath to accomplish this?
The current workaround I have for this is to use a Custom Function to output the first artifact object of the container, but this only creates a snapshot of the artifact object at the time the function is called; If I update the artifact after calling the function, I'll need to call the function again to get the updated artifact object values.
The closest thing I've seen to this is the phantom.collect() API call, in which you can specify a datapath with a specific label (ie. phantom.collect(container, "artifact:uniqueLabel")), where you can specify a label and only the artifacts with the given label is returned, but this same syntax does not work in the Playbook Visual Editor.
For future readers and yourself, the solution I found to this was to use the filter block to obtain a reference to the artifact you need.
For example, in my case I needed a reference to the first artifact in a container, so I made the first artifact always have the label 'main'. Then with a filter node, I do a condition for artifact:*.label == main. Then, in any downstream blocks, you can reference the output of the filter block (which in my case will be any artifact with the label main).
