@rojasyal Thanks for mentioning the version of the modbus library that is compatible with the Node-RED with nodeJS v16.
Did you try to update the nodeJS version from the Dockerfile template?
Let us know about your results!
It doesn’t work for me, it still has version v16.19.1
What did you change @rojasyal ? do you think you can share the Dockerfile so I can try to reproduce?
Thanks!
In the dockerfile I change the version of node.js in the following way but no change appears.
Dockerfile:
Build step
FROM balenalib/raspberrypi3-debian-node:19-bookworm-build as build
WORKDIR /usr/src/app
COPY ./app/package.json package.json
COPY ./app/package-lock.json package-lock.json
RUN JOBS=MAX npm install -g --production --unsafe-perm
node-red
node-red-contrib-balena
&& JOBS=MAX npm install --unsafe-perm --production && npm cache clean --force
Runtime image
FROM balenalib/raspberrypi3-debian-node:19-bookworm-run
RUN apt-get update && apt-get install -yq --no-install-recommends
rpi.gpio
python3-dev
python3-rpi.gpio
libatomic1
git
openssh-client
&& apt-get clean && rm -rf /var/lib/apt/lists/*
Defines our working directory in container
WORKDIR /usr/src/app
Copy over the files created in the previous step, including lib/, bin/
COPY --from=build /usr/local/bin /usr/local/bin
COPY --from=build /usr/local/lib/node_modules /usr/local/lib/node_modules
COPY --from=build /usr/src/app/node_modules /usr/src/app/node_modules
COPY ./ssh_config /etc/ssh/ssh_config
This will copy all files in our root to the working directory in the container
COPY ./app ./
server.js will run when container starts up on the device
CMD [“bash”, “/usr/src/app/start.sh”]
and this is my docker compose

@rojasyal in this repo i’m running Node-RED with nodeJS version v19.6.1
The balena-node-red repo is archived, so my recommendation is to clone it and make the changes to update the nodejs version.
Let me know if that works!
