Splash 3.5 returning "js_source is not implemented"

[danilo4pm]

I'm using splash with docker compose bellow:

version: '3.7'
    services:
      splash:
        image: "scrapinghub/splash:3.5"
        restart: always
        container_name: "splash"
        ports:
          - "8050:8050"
        mem_limit: 1024m
        command: "--disable-private-mode -v3 --js-cross-domain-access --browser-engines=chromium"

Using python requests to query render.html with js_source as said on the documentation page :

import requests

js = """document.querySelector("button[data-tracking='cc-accept']").click();
    document.querySelector("div[data-testid='headerImageClickArea']").click();
    document.querySelector("button.image-gallery-icon.image-gallery-right-nav").click();
"""
url = 'anyurl'
resp = requests.get(f'http://localhost:8050/render.html?url={url}&engine=chromium&js_source={js}')

f = open("./chromium-engine.html", "w")
f.write(str(resp.content))
f.close()
