18-23: Consider adding error messages to custom exceptionsThe custom exception classes
NoCarsFoundExceptionandVinNotFoundExceptioncurrently do not include any messages. Providing meaningful error messages can enhance debugging and make logging outputs more informative.
44-58: Ensure consistent logging levels for exceptionsThere is inconsistent use of logging levels in the exception handling blocks. Some exceptions use
_LOGGER.error, while others use_LOGGER.warning. Consider standardizing the logging levels based on the severity of each exception to maintain consistency.custom_components/polestar_api/translations/en.json (1)
25-25: Minor wording improvementConsider updating the error message from
"Unknown error occurred."to"An unknown error occurred."for better readability and a more user-friendly tone.

33-78: LGTM! Well-structured configuration flow with comprehensive error handlingThe implementation provides clear error handling paths and appropriate user feedback. Consider defining the error dictionary as a class constant to improve maintainability:
class FlowHandler(config_entries.ConfigFlow): VERSION = 1 CONNECTION_CLASS = config_entries.CONN_CLASS_LOCAL_POLL + + ERROR_MAPPING = { + NoCarsFoundException: "no_cars_found", + VinNotFoundException: "vin_not_found", + PolestarAuthException: "auth_failed", + PolestarApiException: "api", + }Then simplify the error handling:
try: await self._test_credentials(username, password, vin) except tuple(self.ERROR_MAPPING.keys()) as exc: _LOGGER.error(exc) _errors["base"] = self.ERROR_MAPPING[type(exc)]
81-102: Add type hint for found_vinsThe implementation looks good, but could benefit from explicit type hinting for better code maintainability.
- found_vins = api_client.vins + found_vins: list[str] = api_client.vins

18-24: LGTM! Well-structured exception classes
The new exception classes are well-defined and follow Python naming conventions. They serve specific error cases which improves error handling granularity.
56-58: Avoid catching the base Exception
Catching the base Exception can mask unexpected errors. Consider catching specific exceptions or removing this catch-all block.
33-78: Verify translation keys exist
Let's ensure all error keys used in the config flow have corresponding translations.
✅ Verification successful
All error keys have corresponding translations in en.json
After checking the error keys used in the config flow:
- "no_cars_found"
- "vin_not_found"
- "auth_failed"
- "api"
- "unknown"
All these error keys are properly defined in the English translation file (en.json) under the "config.error" section with appropriate messages:
"error": {
"auth_failed": "Invalid username/password.",
"no_cars_found": "No cars found for Polestar ID.",
"vin_not_found": "Specified VIN not found for Polestar ID.",
"api": "Error connecting to Polestar API.",
"unknown": "Unknown error occurred."
}🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify translation keys exist for all error messages used in config flow
# Extract error keys from the code
ERROR_KEYS=$(rg -o '"base"\s*:\s*"([^"]+)"' | cut -d'"' -f4 | sort -u)
# Check if these keys exist in the translation file
for key in $ERROR_KEYS; do
echo "Checking key: $key"
rg "\"$key\":" custom_components/polestar_api/translations/
done
Length of output: 75
Script:
#!/bin/bash
# Let's try a different approach to find the error keys and translation files
# First, let's find all translation files
echo "=== Translation files ==="
fd "translations" custom_components/polestar_api/
# Now let's extract error keys from the config flow file directly
echo -e "\n=== Error keys in config_flow.py ==="
rg "_errors\[\"base\"\] = \".*?\"" custom_components/polestar_api/config_flow.py
# Let's also check the content of any translation files if they exist
echo -e "\n=== Content of translation files ==="
fd "translations" custom_components/polestar_api/ --exec cat {}
Length of output: 775
Script:
#!/bin/bash
# Let's check the content of translation files in the translations directory
# Look for English translations (en.json)
echo "=== English translations ==="
fd "en.json" custom_components/polestar_api/translations/ --exec cat {}
# Also check for any other json files in translations
echo -e "\n=== All translation files ==="
fd ".json$" custom_components/polestar_api/translations/ --exec echo "=== {} ===" \; --exec cat {}

33-75: Good error handling structure, but consider minor improvements.The error handling is well-organized with appropriate exception catching and logging. However, consider these improvements:
- Move the
_errors = {}initialization closer to the error handling block- Add more context to error logs, such as including the username in the error messages
Here's a suggested improvement for the error handling section:
async def async_step_user(self, user_input: dict | None = None) -> ConfigFlowResult: """User initiated config flow.""" - _errors = {} if user_input is not None: username = user_input[CONF_USERNAME] password = user_input[CONF_PASSWORD] vin = user_input.get(CONF_VIN) + _errors = {} try: await self._test_credentials(username, password, vin) except NoCarsFoundException as exc: - _LOGGER.error(exc) + _LOGGER.error("No cars found for user %s: %s", username, exc) _errors["base"] = "no_cars_found" except VinNotFoundException as exc: - _LOGGER.error(exc) + _LOGGER.error("VIN not found for user %s: %s", username, exc) _errors["base"] = "vin_not_found"

18-23: LGTM! Well-structured exception classes.
The new exception classes are focused, descriptive, and follow Python naming conventions. They appropriately extend the base Exception class and provide clear semantics for specific error cases.
