issue with pdoPage snippet of pdoTools component

[krava77]

I have two: contexts: web(english) and de(german).

I have an issue with langRouter + pdoPage. It works correctly with web context until I haven't german language in the settings of my browser, but when I add it, the ** /assets/components/pdotools/connector.php** returns an empty result.
Could you help me resolve this issue?

MODx: 3.0.3-pl
langRouter: 1.4.2
pdoTools: 3.0.2-pl

English version located on url: http://localhost:8081/en/
German version located on url: http://localhost:8081/de/

my context settings:
base_url: /
cultureKey: en and de in the de context
url_scheme: https://
site_url: {url_scheme}{http_host}{base_url}{cultureKey}/

I contacted to the langRouter developer but he told that the issue with pdoTools
