You typically can't just copy node_modules with puppeteer to the image.
You should skip node_modules in the .dockerignore and instead run npm install in Dockerfile...
However you will still hit problem with chrome dependencies, so I recommend:

Either use our official images as base
https://jsreport.net/learn/docker#customize-docker-image

Or check how our images are created

I am using jsreport latest docker image and mounted the data and configuration files to container. I am not able to render pdf because of below error

Could not find Chrome (ver. 121.0.6167.85). This can occur if either

you did not perform an installation before running the script (e.g. npx puppeteer browsers install chrome) or
your cache path is incorrectly configured (which is: /app/.puppeteer-cache).
For (2), check out our guide on configuring puppeteer at https://pptr.dev/guides/configuration.

You could be running jsreprot with a different user than the one that was used to install the puppeteer.
Please share your updated dockerfile.

This is the dockerfile

Use the jsreport/jsreport image version 4.2.0 as the base image
FROM jsreport/jsreport:latest-full

USER root

COPY . .

CMD [ "npm", "start" ]

COPY --chown=jsreport:jsreport /data /app/data

I used this docker file and it works fine. But I was using the code you fixed related to preprocessing in xlsx https://forum.jsreport.net/topic/3030/change-in-file-type-after-importing-xlsx-file/6 post install. As I am not able to modify loop.js in node_modules inside docker, is there any way to get those changes now?

admin

Create a local folder, let's say patch, and put the changes you need to copy to the image there.
For example

patch/node_modules/@jsreport/jsreport-xlsx/lib/generation/preprocess/loop.js

Then add a docker build step

COPY --chown=jsreport:jsreport patch /app

Thanks a lot, worked for me.
In my local environment, I'm able to successfully render a PDF with 12 charts distributed across two pages. However, when I attempt to replicate this within a Docker container, the output changes and I end up with each chart occupying a separate page. Is there any way to fix this?
