Multi-Stage Docker build failed - Error: invalid from flag value

Question

I am trying to implement multi-stage docker build to deploy Django web app. An error occurred while trying to copy files from one docker stage to another. I am sharing Dockerfile and error traceback for your reference.

The same Docker build worked before one day ago. Somehow, It is not working today. I have searched for some workaround. But, no luck.

My Dockerfile as:

FROM node:10 AS frontend
ARG server=local
RUN mkdir -p /front_code
WORKDIR /front_code
ADD . /front_code/
RUN cd /front_code/webapp/app \

    && yarn list && ls -l /front_code/webapp/app/static \
    && npm run build \

Note: 1) I have a free version of Docker account. 2) I am using AWS Codepipeline to build and deploy. 3) Docker version is 19.03.3.
