We are trying to use jsreport on AWS via Lambda functions but we are stuck with a module problem.
You can see below our project directories :

The custom modules are saved in the scripts folder.

When i try to require a custom module in one of my report content.js, I got the following error on AWS (everything is working well locally and the scripts folder is well uploaded to /var/tasks/scripts/... on my lambda).

{
  "errorType": "Error",
  "errorMessage": "Error while executing user script.

Do you have any idea ?

Thanks a lot,

Regards,

const path = require('path')
const myModule = require(path.join(__appDirectory,  'scripts/database/afpdb'))

Thanks for the quick reply.

After more digging, it appears that my modules are found but not formatted as you expect.

Actually, this is not working :

'use strict';

const _createAccess1 = require('module1');
const _createAccess2 = require("module2");
const _createAccess3 = require('module3');
const _config = require("config");
const _mongoose = require('mongoose');

module.exports = function () {
...
}

but this is working :

'use strict';

module.exports = function () {
    const _createAccess1 = require('module1');
    const _createAccess2 = require("module2");
    const _createAccess3 = require('module3');
    const _config = require("config");
    const _mongoose = require('mongoose');

....
}
