[D] Superset get screenshot occurred error [superset]
GitHub user moshhi created a discussion: Superset get screenshot occurred error
I added conf to superset_config.py:
SCREENSHOT_LOCATOR = "https://localhost:8088/"
ENABLE_CELERY_REPORTS = True
WEBDRIVER_TYPE = "chrome"
WEBDRIVER_OPTION_ARGS = [
"--headless",
"--disable-gpu",
"--no-sandbox",
"--disable-dev-shm-usage",
]
WEBDRIVER_CONFIGURATION = {
"service": {
"executable_path": "/usr/local/bin/chromedriver",
"log_output": "/var/log/superset",
"service_args": [],
"port": 0,
"env": {},
},
"options": {
"capabilities": {},
"preferences": {},
"binary_location": "",
},
}
but occurred another exception：
The above exception was the direct cause of the following exception:

The error "'dict' object has no attribute 'path'" happens because the WEBDRIVER_CONFIGURATION in your superset_config.py is being passed directly to Selenium, which expects certain values (like executable_path) to be a string, not a dict. If any of these values are accidentally set as a dict, Selenium tries to access a .path attribute on them, causing this error. This is a common pitfall when merging or editing config files for Selenium in Superset [[source](https://github.com/apache/superset/blob/b9052fa46173b0172c7f4349ed0194e441a97ed8/superset/utils/webdriver.py)].
To fix this, make sure your WEBDRIVER_CONFIGURATION looks like this:
```python
WEBDRIVER_CONFIGURATION = {
"service": {
"executable_path": "/usr/local/bin/chromedriver", # must be a string path
"log_output": "/dev/null", # or your preferred log location
"service_args": [],
"port": 0,
"env": {},
},
"options": {
"capabilities": {},
"preferences": {},
"binary_location": "",
},
}
```
Double-check that executable_path is a string and not a dict or any other type. Also, avoid using WEBDRIVER_EXECUTABLE_PATH, as Superset ignores it [[source](https://github.com/apache/superset/discussions/34053)].
For stability, you can add these recommended options:
```python
WEBDRIVER_OPTION_ARGS = [
"--headless",
"--no-sandbox",
"--disable-gpu",
"--disable-dev-shm-usage",
"--disable-setuid-sandbox",
"--start-maximized",
]
```
If you still see issues, try increasing the screenshot wait times:
```python
SCREENSHOT_LOCATE_WAIT = 30
SCREENSHOT_LOAD_WAIT = 60
```
[[source](https://github.com/apache/superset/issues/33602)]
After updating your config, restart your Superset services and try again. This should resolve the error.
