For this error, it is caused that node is not installed in mcr.microsoft.com/dotnet/core/aspnet:3.0-stretch-slim image, try to change your dockerfile to install node with version 10 or later.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.0-stretch-slim AS base
# BEGIN MODIFICATION - Node is needed for development (but not production)
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash -
RUN apt-get install --assume-yes nodejs
# END MODIFICATION

WORKDIR /app
EXPOSE 80
