Build error while deploying

[Alexandros]

fly deploy works great locally but fails when i am running this action

i have tried adding ENV DOCKER_BUILDKIT=1 to the Dockerfile but i still get the same error

Error failed to fetch an image or build from source: error building: error rendering build status stream: the --mount option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled

workflow file

name: Fly Deploy
on: [push]
env:
  FLY_API_TOKEN: ${{ secrets.FLY_API_TOKEN }}
jobs:
  deploy:
    name: Deploy app
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: superfly/flyctl-actions/setup-flyctl@master
      - run: flyctl deploy

what fixed it was adding the --remote-only to flyctl deploy
