I am trying to build a docker image based on this repo:
https://github.com/TechPreacher/iotedge-lorawan-starterkit-decoders
But the repo seems to have error in the docker files:
When I build the image using right click on Module.json Build IoT Edge Module Image I get this output:

One screenshot of my folder structure:
I tried running the docker build command inside the DecoderCollection folder which has the .csproj but its the same error.
docker file@
FROM microsoft/dotnet:2.1-sdk AS build-env
#WORKDIR /DecoderCollection/
#COPY ./Samples/DecoderSample ./
RUN dotnet restore
RUN dotnet publish -c Release -o out
FROM microsoft/dotnet:2.1-aspnetcore-runtime-stretch-slim-arm32v7 AS runtime
WORKDIR /app
COPY --from=build-env /build/Samples/DecoderSample/out/* ./
ENTRYPOINT ["dotnet", "SensorDecoderModule.dll"]
