Goal: Port flag error tracking to React Native by including the $feature_flag_error property in $feature_flag_called events. This property exists to help debug flag evaluation failures.
The value of the property reflects any error(s) that occurred while retrieving remote evaluation results from the /flags endpoint.
Other SDKs report properties such as:
errors_while_computing_flags - Server response body JSON included errorsWhileComputingFlags=trueflag_missing - Requested flag not in API responsequota_limited - Rate/quota limit exceededtimeout - Request timed outconnection_error - Network connectivity issueapi_error_{status} - Server error with HTTP status code (e.g., api_error_500)unknown_error - Unexpected exceptions
Multiple relevant errors are joined with commas (e.g., errors_while_computing_flags,flag_missing).
This feature has been implemented in a number of SDKs already for reference:
