Hi,
I'm using a customized jsreport dockerfile, to run jsreport on a container. When it renders a chrome-pdf template, it fails with the following error:

I'm using the following dockerfile:

FROM jsreport/jsreport:3.7.1-full AS builder-image
WORKDIR /var/lib/nimbus-report-template
COPY src ./src
COPY package*.json ./
COPY .npmrc ./
COPY jsreport.config.json ./
RUN npm i
RUN npm install -g rimraf

FROM jsreport/jsreport:3.7.1-full AS runtime-image
WORKDIR /var/lib/nimbus-report-template
COPY --from=builder-image ./var/lib/nimbus-report-template .
CMD npm start

and set the extension config:

  "chrome": {
    "timeout": 36000
  },
  "extensions": {
    "chrome-pdf": {
      "timeout": 36000,
      "launchOptions": {
        "timeout": 36000,
        "args": ["--no-sandbox"]
      }
    },

Thanks.

Re: [json file](get data from script)

Hi,
I see that 4 years ago, the solution for getting a json file's content in a script was to use readFileSync.
Is there a way to use --resolveJsonModule somehow, so I'll be able to require the file like this:

import * as mockedFetchData from './mockedFetchData.json';

I'm still trying to fully figure out the jsreport capabilities, so I'm challenging it to determine the limits.
Thanks.

ShlomitG

ok, so actually I use afterRender to fetch the data in chunks, render the chunks and then use the append operation to concatenate the render responses. Just as explained in the documentation (https://jsreport.net/learn/pdf-utils, 'Usage in script' section).
The problem is that append operation adds a page break, so the data chunks are appended in the final pdf but with page breaks. How can I avoid it, and append the data consecutively?

ShlomitG

Thanks.
Is there a way to send the render data as a blob, or it must be a json?
since I need to render a huge amount of data, and the node is incapable of defining such a big variable

Hi,
I'm trying to generate a report, sending 4mb data data in the /render.
After a few minutes, the generation fails, and I get the following log error:

When I use the same /render for 1mb data - it's working.
I don't think it's a timeout issue - because I already handled it.
It doesn't look like memory issue either.
There is no error here, so I don't know where to search.
Can I get some help, please?

Thanks
