Hello,
My service "frontend" in project signifex-shop fails to build consistently for the past hour, across 5+ consecutive attempts, with two different errors depending on the attempt:
Most recent error (build ID ac253d6c, 2026-08-05 12:50 GMT+2):
Build Failed: build daemon returned an error < failed to solve: failed to compute cache key: failed to calculate checksum of ref nts0ru0lq536bnrt42bo9ft3k::s5gxfk588jwidfd4yelv7tuyb: "/frontend": not found >
This happens at the "COPY frontend/ ./" step of the Dockerfile, while previous steps using the same folder (COPY frontend/package.json...) are marked "cached" without issue. The frontend/ folder is definitely present in my GitHub repo (edouardwilssonn-sketch/signifex-shop, main branch) — I've verified this.
Earlier attempts failed with a different error:
container process is already dead / context canceled
also at the very first Dockerfile command, on a Dockerfile that worked fine for the previous 5 deployments.
Builder involved: builder-wvldab (Metal builder), US West / sfo region.
Could you check if there's a known issue with build cache or the Metal builder infrastructure right now? An option to force a build without cache would also help in the meantime.
Thank you,

Your service is configured to use the Railpack builder with a root directory of frontend, not a Dockerfile, so the COPY frontend/ ./ step you are describing would not apply to this service's actual build pipeline. If you intend to use a Dockerfile, you can switch the builder in the service's settings. To force a build without cache, add the environment variable NO_CACHE=1 to the service and redeploy.
