It seems to have something to do with an array I'm passing in the data. I changed it to pass the data stringified and it seems to work fine now.

jsreport.render({
  template: {
    name: 'reportName'
  },
  data: JSON.stringify({...}),
  options: {
    localization: { language: 'en' },
  }
});

Thank you!

Sorry, I forgot to copy that line in my previous post but I was actually calling jsreport.init. The code works fine in the development environment, but I get that error when I run it from the dist directory and the whole application crashes. I have checked the paths to the data directory in the jsreport startup logs and it is correct. However, I get the same error if I set up a data directory that doesn't exist.

const options = {
  logger: {
    file: { transport: "file", level: "debug", filename: '/logs/log' },
    error: { transport: "file", level: "error", filename: '/logs/error.log' },

  },
  store: { provider: 'fs' },
  extensions: {
    "fs-store": {
      dataDirectory: '/data',
      externalModificationsSync: false,
      enabled: true
    }
  }
};

const jsreport = require('@jsreport/jsreport-core')(options);
jsreport.use(require('@jsreport/jsreport-assets')());
jsreport.use(require('@jsreport/jsreport-chrome-pdf')());
jsreport.use(require('@jsreport/jsreport-data')());
jsreport.use(require('@jsreport/jsreport-fs-store')());
jsreport.use(require('@jsreport/jsreport-jsrender')());
jsreport.use(require('@jsreport/jsreport-pdf-utils')({ syncModifications: false }));
jsreport.use(require('@jsreport/jsreport-localization')());

await jsreport.init();

await jsreport.render({
  template: {
    name: 'reportName'
  },
  data: {...},
  options: {
    localization: { language: 'en' },
  }
});

Sorry, but I don't have the code on github and I can't upload the whole project right now. Maybe I can try to make a repository with part of the code.

Hi, I am deploying an application that renders a report from javascript and I get the following error. I have tried to place the data directory in different places and I get the same error in all of them.

DOMException [DataCloneError]: [object Array] could not be cloned.

This is the code I use to render the report.

const options = {
  logger: {
    file: { transport: "file", level: "debug", filename: '/logs/log' },
    error: { transport: "file", level: "error", filename: '/logs/error.log' },

  },
  store: { provider: 'fs' },
  extensions: {
    "fs-store": {
      dataDirectory: '/data',
      externalModificationsSync: false,
      enabled: true
    }
  }
};

const jsreport = require('@jsreport/jsreport-core')(options);
jsreport.use(require('@jsreport/jsreport-assets')());
jsreport.use(require('@jsreport/jsreport-chrome-pdf')());
jsreport.use(require('@jsreport/jsreport-data')());
jsreport.use(require('@jsreport/jsreport-fs-store')());
jsreport.use(require('@jsreport/jsreport-jsrender')());
jsreport.use(require('@jsreport/jsreport-pdf-utils')({ syncModifications: false }));
jsreport.use(require('@jsreport/jsreport-localization')());

jsreport.render({
  template: {
    name: 'reportName'
  },
  data: {...},
  options: {
    localization: { language: 'en' },
  }
});

Thank you very much @bjrmatos! That was the problem.

Hi, I'm trying to use jsreport.localization.localize as shown in the example in the "Complex use case" of the localization documentation (https://jsreport.net/learn/localization) and it works fine when I use the studio, but when I render the report from Javascript code I get this error:

TypeError: Cannot read properties of undefined (reading 'localize')

One reason may be that I'm using jsreport-core to render from Javascript. I don't know if it has something to do with the error.

const jsreport = require('@jsreport/jsreport-core')(options);
jsreport.use(require('@jsreport/jsreport-assets')());
jsreport.use(require('@jsreport/jsreport-chrome-pdf')());
jsreport.use(require('@jsreport/jsreport-data')());
jsreport.use(require('@jsreport/jsreport-fs-store')());
jsreport.use(require('@jsreport/jsreport-jsrender')());
jsreport.use(require('@jsreport/jsreport-pdf-utils')({ syncModifications: false }));

jsreport.render({
      template: {
        name: reportName
      },
      data,
      options: {
        localization: { language: 'en' },
      }
    });

One thing I've noticed is that when printing the jsreport-proxy properties in the helper, it does not have the 'localization' property when rendering form JS, whereas that property exists when rendering from the studio.

const jsreport = require('jsreport-proxy');
console.log(Object.keys(jsreport));

Is there anything else I need to import in order to use the localize function in the helper?

Thank you.
