How to Dockerize CodeEffects Rules Engine Angular Implementation

Question

We are using CodeEffects Rules Engine with Angular Implementation and trying to dockerize the application. But the build is throwing an exception; need help from this group in resolving the error.

Below is my docker script and also attaching the error screenshot for reference

NOTE: Application works fine without docker in local.

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env

RUN apt-get update && \
apt-get install -y wget && \
apt-get install -y gnupg2 && \
wget -qO- https://deb.nodesource.com/setup_12.x | bash - && \
apt-get install -y build-essential nodejs

WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "CodeEffects.Rule.Angular.Demo.dll"]
