[Need support]: Healenium: Saving elements does not execute for outside driver

[Alek5andr]

Describe the problem

Hi!

I have a problem with storing elements' selectors into PostgreSQL while running Healenium's services in Docker and Selenium's services locally.

Here is the thing:
I start PostgreSQL, Healenium, Healenium-Proxy and selector-imitator in Docker on local machine. The Docker's configuration file is provided. Then I start downloaded standalone chromedriver (simply put chromedriver) version 134 also locally with the command chromedriver --port=4444 --allowed-ips --verbose. After that I launch WebdriverIO example of "healenium-example-webdriverio" by executing the command npm run wdio. "wdio.conf.js" file contains properties for Healenium-proxy:

    services: [],
    hostname: '192.168.1.222', // local machine IP-address
    port: 8085,
    protocol: 'http',

Test runs fine - successfully. Chromedriver accepts requests and gives responds. Healenium-Proxy initializes a session successfully:

Init Session: {"value":{"capabilities":{"acceptInsecureCerts":true,"browserName":"chrome","browserVersion":"134.0.6998.178","chrome":{"chromedriverVersion":"134.0.6998.165 (fd886e2cb29dd984c13deec032832dee68d8abe3-refs/branch-heads/6998@{#2122})","userDataDir":"C:\\Users\\ALEKSA~1\\AppData\\Local\\Temp\\scoped_dir26372_87912565"},"fedcm:accounts":true,"goog:chromeOptions":{"debuggerAddress":"localhost:63989"},"networkConnectionEnabled":false,"pageLoadStrategy":"normal","platformName":"windows","proxy":{},"setWindowRect":true,"strictFileInteractability":false,"timeouts":{"implicit":0,"pageLoad":300000,"script":30000},"unhandledPromptBehavior":"ignore","webSocketUrl":"ws://192.168.1.222:4444/session/77fdd4c6664102728fc34c077e8fa171","webauthn:extension:credBlob":true,"webauthn:extension:largeBlob":true,"webauthn:extension:minPinLength":true,"webauthn:extension:prf":true,"webauthn:virtualAuthenticators":true},"sessionId":"77fdd4c6664102728fc34c077e8fa171"}}

But Heleanium itself does not save elements. It only makes "Get Elements".
Healenium-Proxy just generates an empty result in the end.
That's all. No stored selectors.

HOWEVER
If I stop local chromedriver and create&run another container consisting of "selenium/standalone-chrome:latest":

chrome2in1:
    image: selenium/standalone-chrome:latest
    container_name: standalone-chrome
    shm_size: 2gb
    ports:
    - "4444:4444"
    - "7900:7900"

then Healenium save elements successfully! How? Why? I could not figure it out.
Searching for a help, how does Healenium decides to store elements.
