<!-- Answer --> Your configuration changes aren't being applied because in Docker Compose setups, Superset only loads custom configs from `docker/pythonpath_dev/superset_config_docker.py`—not from `app/superset/config.py` or similar paths. You should copy your config (for example, from `docker/pythonpath_dev/superset_config_local.example`) to `docker/pythonpath_dev/superset_config_docker.py` and put your `WEBDRIVER_CONFIGURATION` there. This will ensure Superset actually uses your settings for Selenium and resolves the AttributeError you’re seeing. More details are in the [official Docker docs](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docs/docs/installation/docker-compose.mdx) and [config loader code](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docker/pythonpath_dev/superset_config.py). Also, double-check that your `WEBDRIVER_CONFIGURATION` matches the expected structure: the `service` section should use `log_path` (not `log_output`), and the `options` section should be a dictionary with `capabilities` and `preferences` keys. Superset’s code expects these to be set on a Selenium Options object, not as a plain dict—so the config must be loaded correctly for this to work ([reference](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/utils/webdriver.py)). Let me know if you need an example config file or further help! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
