LUA script doesn't return evaljs content on Ubuntu 16.04.

I am trying to scrap the HTML and the Window object from site using Splash V.3.3.1. Locally on OSX environment it works perfectly but when I deploy to Ubuntu 16.04 production server LUA scripts return the object only with ‘html’ key.

def parse(self, response):
    print(response.data)

Result:

{'html': 'ALL HTML'}

Script:

    def start_requests(self):
        """Starting place for request."""
        script = """
        function main(splash, args)
          assert(splash:go(args.url))
          assert(splash:wait(0.5))
          local data = splash:evaljs("window.typeOfObject")
          return {
            js = data,
            html = splash:html()
          }
        end
        """
        yield SplashRequest(self.url, self.parse, endpoint='execute', args={
            'wait': 1,
            'proxy': 'http://localhost:24000',
            'lua_source': script
        })

Did you ever find a solution @laranicolas ? Having the same exact issue here.

When looking more specific under window js object

script = """
        function main(splash, args)
          assert(splash:go(args.url))
          assert(splash:wait(0.5))
          local data = splash:evaljs("window. typeOfObject.data.overview)
          return {
            js = data,
            html = splash:html()
          }
        end
        """

it raises undefined error:

2019-05-23 19:10:30 [scrapy_splash.middleware] WARNING: Bad request to Splash: {'info': {'line_number': 5, 'error': 'JS error: "TypeError: undefined is not an object (evaluating \'window. typeOfObject.data.overview\')"', 'message': '[string "..."]:5: JS error: "TypeError: undefined is not an object (evaluating \'window. typeOfObject.data.overview\')"', 'source': '[string "..."]', 'js_error': "TypeError: undefined is not an object (evaluating 'window. typeOfObject.data.overview')", 'splash_method': 'evaljs', 'type': 'JS_ERROR', 'js_error_type': 'TypeError', 'js_error_message': "undefined is not an object (evaluating 'window. typeOfObject.data.overview')"}, 'description': 'Error happened while executing Lua script', 'error': 400, 'type': 'ScriptError'}

but if I did on site it show the information using same js variable, also if I run locally it works…, really I don’t know what could be?
