How to tag an image with an automatic annotation?
I have a model deployed in nuclio and would like to return a tag if an element is, for example, not detected in an image.

Current Behaviour

I tried to return a JSON stating that the type is a tag, but this results in an error.
My current workaround is to return a rectangle for the entire image, which states that the element is not in the image.

Expected Behaviour

Returning and adding a tag from the automatic annotation would be nice.

Example return JSON with a tag instead of a rectangle/polygon/point:

[
    {
        "confidence": "0.9999131",
        "label": "not found element",
        "type": "tag"
    }
]
