custom catch exception

example

def register_exception(app: FastAPI):
    @app.exception_handler(BaseHTTPException)
    async def catch_c_http_exception(request: Request, exc: BaseHTTPException):
        """catch custom exception"""

        log_message(request, exc.message)
        content = {'status_code': exc.CODE, 'message': exc.message, 'data': None}
        return JSONResponse(content=content, status_code=exc.status_code, headers=exc.headers)

    @app.exception_handler(Exception)
    async def exception_handle(request: Request, exc: Exception):
        """catch other exception"""

        log_message(request, traceback.format_exc())
        content = {'status_code': StatusCode.server_error, 'message': str(exc), 'data': None}
        return JSONResponse(content=content, status_code=status.HTTP_500_INTERNAL_SERVER_ERROR)

@panla , this not help me. I dont know what libs i need import to test it. Can you help me ?

[panla]

if you write some error/bug code (print(1 / 0)) in your api. this can catch exception

another is cors middleware
