I'm using the provided example here: https://github.com/docker/scout-action#build-an-image-push-and-compare to run docker scout, but if the output from metadata-action steps.meta.outputs.tags contains multiple tags it's output as a multi-line string and this leads to the scout action giving an error:

Error: could not get the image <image-name-redacted>:latest
  <image-name-redacted>:<some-version>: failed to parse reference <image-name-redacted>:latest
  <image-name-redacted>:<some-version>:

Is this supposed to work?
