2025-09-08T04:07:27,207   Possible solutions:
2025-09-08T04:07:27,207   	1. Declare '_error_handler' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
2025-09-08T04:07:27,207   	2. Use an 'int' return type on '_error_handler' to allow an error code to be returned.
