is there a better way to get the fisrt tag?

JSON output
  {
    "tags": [
      "***/process-exporter:v0.7.11",
      "***/process-exporter:latest"
    ],

workflow:

      - name: generate docker metadata
        id: meta
        uses: docker/metadata-action@v5
        with:
          # list of Docker images to use as base name for tags
          images: |
            xxx/process-exporter
          # generate Docker tags based on the following events/attributes
          tags: |
            type=schedule
            type=ref,event=branch
            type=ref,event=pr
            type=semver,pattern={{raw}}

      - name: Extract first Docker image tag
        id: first_tag
        run: echo "tag=$(echo '${{ steps.meta.outputs.tags }}' | awk '{print $1;exit}')" >> $GITHUB_OUTPUT

You can use steps.meta.outputs.version

first full name:

${{ fromJSON(steps.meta.outputs.json).tags[0] }}

there is a demo:

      - name: Scan with Trivy
        uses: aquasecurity/trivy-action@master
        with:
          image-ref: ${{ fromJSON(steps.meta.outputs.json).tags[0] }}
