Thank you so much for your reply, Graig!
It was about an indent error. Now, I have another issue.
Is it about a space issue on the Dyno? or an installation error? It seems relevant to a kind of generic troubleshoot... but if you could look at it and give me your first thought, it will be helpful. Even if not, it will be OK.

Thank you and I look forward to your feedback.

I figured it out. V8 of nodejs has been deprecated. I changed the version in Dockerfile

RUN apt-get -y install curl \
  && curl -sL https://deb.nodesource.com/setup_8.x | bash \
  && apt-get install nodejs \
  && curl -o- -L https://yarnpkg.com/install.sh | bash

into

RUN apt-get -y install curl \
  && curl -sL https://deb.nodesource.com/setup_12.x | bash \
  && apt-get install nodejs \
  && curl -o- -L https://yarnpkg.com/install.sh | bash

I hope this will help others who may give it a try.

Most of all, thank you for your posting and feedback to my questions, Craig!
