I've been chasing a 500: INTERNAL_SERVER_ERROR, code: FUNCTION_INVOCATION_FAILED with my backend using python. It's saying its a handler issue. My handler code is below. Can you help with the issue?
def handler(event, context): asgi_handler = Mangum(app, lifespan="off") return asgi_handler(event, context)
