Error parsing list of instance when empty response

[chrisdemers]

I have the error 'jq: error (at :1): Cannot index boolean with string "instance_name"' when get instances request returns empty list

list_response=$(curl -X GET \
            -H "ls-api-key: ${LOCALSTACK_AUTH_TOKEN:-${LOCALSTACK_API_KEY:-${{ inputs.localstack-api-key }}}}" \
            -H "content-type: application/json" \
            https://api.localstack.cloud/v1/compute/instances)

instance_exists=$(echo "$list_response" | jq --arg NAME "$previewName" '.[] | select(.instance_name == $NAME)')

Action call:

          uses: LocalStack/setup-localstack@v0.2.4
          with:
            github-token: ${{ secrets.GITHUB_TOKEN }}
            use-pro: true
            install-awslocal: true
            include-preview: false
            skip-ephemeral-stop: true
            state-backend: ephemeral
            state-action: start
            preview-cmd: awslocal s3api create-bucket --bucket test-devops-local
          env:
            LOCALSTACK_API_KEY: ${{ secrets.LOCALSTACK_AUTH_TOKEN }}      

It works when I manually create an ephemeral instance manually before triggering my workflow
