Randomly started to get this error upon deploy. Already tried to clear docker cache in the builder, setting cache ignore in the docker file. nothing solves it

cat << ‘EOF’ > deploy_to_fly.sh

#!/usr/bin/env bash

flyctl deploy . --remote-only --no-cache \

–access-token “***” \

–dockerfile “./apps/nodejs-server/Dockerfile” \

–config “./apps/nodejs-server/fly.toml” \

–build-secret NPM_TOKEN=“***”

I fixed this error by specifying the exact docker file version at the top instead of version “1”

# syntax = docker/dockerfile:1.4.0
