Hello, I think I had the exact same issue while trying to deploy the forest admin backend to an ECS cluster in AWS. The installation could not complete because the file .forestadmin-schema.json was not found.
I was using the Dockerfile generated with the project:
FROM node:10-alpine
WORKDIR /usr/src/app
# install node_modules in another directory to easy mount folder for develoment purpose
ENV NODE_PATH=/usr/src/node_modules
COPY . .
RUN npm install -s --prefix /usr/src .
EXPOSE ${APPLICATION_PORT}
CMD ["npm", "start"]
At some point I had no clue what was going on and try to remove the part where the NODE_PATH is changed “for development purpose”. I then used the following Dockerfile and the error was gone and the file got found.
FROM node:10-alpine
WORKDIR /usr/src/app
COPY . .
RUN npm install
EXPOSE ${APPLICATION_PORT}
CMD ["npm", "start"]
I hope this can help you if you read this tread to the bottom
