HELP: Visual Studio Docker container fast mode with GitHub Actions

Question

Hello everyone!

I've a weird issue with docker build in combination with GitHub actions. I'm totally new with Docker files and I really, really, really appreciate some help.

When running the command on my CLI, it works perfectly fine. But when trying it on GitHub action, I'm receiving the error:

unable to prepare context: path "..." not found Error: Process completed with exit code 1.

Command:

cd services/Gateway/OcelotGateway 
docker build -f Dockerfile ... -t stanpanman/ocelotgateway:1.0.0

My GitHub Actions as follows:

build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: docker login
        env:
          DOCKER_USER: '${<!-- -->{ secrets.DOCKER_USER }}'
          DOCKER_PASSWORD: '${<!-- -->{ secrets.DOCKER_PASSWORD }}'
        run: |
          docker login -u $DOCKER_USER -p $DOCKER_PASSWORD
      - name: docker build ocelotgateway
        run: |
          cd services/Gateway/OcelotGateway 
          docker build -f Dockerfile ... -t stanpanman/ocelotgateway:1.0.0

My Docker image (auto generated by VS2022 :

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY ["Gateway/OcelotGateway/OcelotGateway.csproj", "Gateway/OcelotGateway/"]
RUN dotnet restore "Gateway/OcelotGateway/OcelotGateway.csproj"
COPY . .
WORKDIR "/src/Gateway/OcelotGateway"
RUN dotnet build "OcelotGateway.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "OcelotGateway.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "OcelotGateway.dll"]

How my file structure looks like:
