SUPERSET ALERT & REPORT: no chrome binary at /usr/bin/google-chrome

[bnprayoga]

Hi,

I'am new as programmer and i'am also new on Superset.
I have an issue on Superset Alert and Report, that says: Failed taking a screenshot Message: session not created from unknown error: no chrome binary at /usr/bin/google-chrome

but i think i have installed it properly because when i run comand: which google-chrome and which chromedriver it works and show the location on /usr/bin/google-chrome and /usr/bin/chromedriver.

below is the full error logs:

Another info:

• i am using apache superset version 5.0.0

Hi @bnprayoga! I'm Dosu and I’m helping the superset team.

The error means Superset (via Selenium) can't find or run Chrome at /usr/bin/google-chrome, even though your shell can. This usually happens because the Celery worker process runs with a different environment or permissions than your shell.

Here’s how to fix it:

1. Check permissions: Run ls -l /usr/bin/google-chrome and make sure the user running Superset and Celery can execute it.

2. Version match: Make sure your Chrome and ChromeDriver versions match exactly. Run google-chrome --version and chromedriver --version to check.

3. Configuration: Superset expects the Chrome binary path in the WEBDRIVER_CONFIGURATION dictionary, not just as CHROME_BINARY_LOCATION. Update your superset_config.py like this:

   WEBDRIVER_TYPE = "chrome"
   WEBDRIVER_OPTION_ARGS = [
       "--force-device-scale-factor=2.0",
       "--high-dpi-support=2.0",
       "--headless",
       "--disable-gpu",
       "--disable-dev-shm-usage",
       "--no-sandbox",
       "--disable-setuid-sandbox",
       "--disable-extensions",
   ]
   WEBDRIVER_CONFIGURATION = {
       "service": {
           "executable_path": "/usr/bin/chromedriver",
           "log_output": "/dev/null",
           "service_args": [],
           "port": 0,
           "env": {},
       },
       "options": {
           "capabilities": {},
           "preferences": {},
           "binary_location": "/usr/bin/google-chrome",
       },
   }

   Reference

4. Restart everything: After changing config, restart both Superset and all Celery workers so they pick up the new settings.

5. Environment: If you’re running Superset and Celery in a virtual environment, make sure both are started from the same shell/environment so they see the same PATH and config.

If you still get errors, check for system restrictions (like SELinux/AppArmor), and confirm that /usr/bin/google-chrome is executable by the Superset/Celery user.

If Selenium keeps failing, you can switch to Playwright for screenshots and reports by setting PLAYWRIGHT_REPORTS_AND_THUMBNAILS = True in your config and installing the playwright Python package. Playwright is often more robust in tricky environments.

Let me know if you need help with any of these steps!
