Unexpected error about superset HOT 2 OPEN

To resolve the "Unexpected error" message that appears when opening different pages in Apache Superset, which goes away upon refreshing the page, you can use the find_unexpected_errors method from the WebDriverPlaywright or WebDriverSelenium classes to capture and handle these errors. This method identifies alert elements on the page and logs the error messages.

Here is an example of how you can use the find_unexpected_errors method to capture and log unexpected errors:

from superset.utils.webdriver import WebDriverPlaywright, WebDriverSelenium

# Example using WebDriverPlaywright
def capture_errors_with_playwright(page):
    unexpected_errors = WebDriverPlaywright.find_unexpected_errors(page)
    if unexpected_errors:
        for error in unexpected_errors:
            print(f"Unexpected error found: {error}")

# Example using WebDriverSelenium
def capture_errors_with_selenium(driver):
    unexpected_errors = WebDriverSelenium.find_unexpected_errors(driver)
    if unexpected_errors:
        for error in unexpected_errors:
            print(f"Unexpected error found: {error}")

You can integrate these methods into your existing code where you handle page loads to ensure that any unexpected errors are captured and logged, which can help in diagnosing and resolving the issue.

Additionally, you can leverage the error handling mechanisms provided in superset/views/base.py to better manage and log errors. For example, the json_error_response and json_errors_response functions can be used to format error messages consistently. You can also use the show_unexpected_exception function to handle unexpected exceptions and log them appropriately.

Here is an example of how you can use these functions:

from superset.views.base import json_error_response, json_errors_response, show_unexpected_exception
from superset.errors import SupersetError, SupersetErrorType, ErrorLevel

def handle_unexpected_error(ex):
    error = SupersetError(
        message=str(ex),
        error_type=SupersetErrorType.GENERIC_BACKEND_ERROR,
        level=ErrorLevel.ERROR,
    )
    return json_errors_response(errors=[error], status=500)

try:
    # Your code that might raise an unexpected error
    pass
except Exception as ex:
    response = handle_unexpected_error(ex)
    print(response.get_data(as_text=True))

By using these built-in error handling functions, you can ensure that errors are logged and formatted consistently, making it easier to diagnose and resolve issues in Apache Superset ^[1][2].
