github action buildah fails to pull docker image

Question

running buildah github action to build the container below

FROM docker.io/library/dart:stable AS build

COPY . /app
WORKDIR /app
RUN dart compile exe ./bin/server.dart -o ./server

FROM scratch
COPY --from=build /runtime/ /
COPY --from=build /app/ /bin

EXPOSE 8080
CMD ["server"]

I get this error
