Electron PDF timeout in AWS EC2 t2.medium instance (dual core) | configuration help

Issue

I'm trying to generate a report via electron-pdf and it's timing out with the following error:

Error: Timeout when executing in electron
    at Timeout._onTimeout (/home/ubuntu/jsreportapp/node_modules/electron-html-to/lib/dedicatedProcessStrategy.js:277:20)
    at ontimeout (timers.js:498:11)
    at tryOnTimeout (timers.js:323:5)
    at Timer.listOnTimeout (timers.js:290:5)

Would very much appreciate any assistance :pray:

Steps

I installed jsreport-electron-pdf and electron since electron-prebuilt is now Deprecated.
Here's the extract from my package.json:

"dependencies": {
    "electron": "^2.0.5",
    "install": "^0.12.1",
    "jsreport": "2.1.1",
    "jsreport-electron-pdf": "^3.0.0",
    "jsreport-phantom-pdf": "^2.1.3",
    "npm": "^6.2.0"
  }

and here's the section from my jsreport.config.json file:

"extensions": {
    "authentication": {
      "cookieSession": {
        "secret": "some secret"
      },
      "admin": {
        "username": "some name",
        "password": "some password"
      },
      "enabled": true
    },
    "scripts": {
      "timeout": 40000,
      "strategy": "http-server"
    },
    "electron":{
      "strategy":"electron-ipc",
      "pingTimeout":100,
      "timeout":5000
    }
  },

Description

I'm running on an AWS EC2 t2.medium instance so that has 2 cores
However the electron-pdf strategy is defaulting to dedicated-process even though I'm setting it as electron-ipc in the jsreport "extensions" configuration.
It's not even taking the pingTimeout and timeout values from the config file

Tried to get help on the jsreport-electron-pdf github repo but not sure if that's really active
