	onGenerationStart: (generationInfo) => {
        logger.traceGeneration("trace-id", generationInfo);
    },
	onGenerationEnd: (generationId, result) => {
		logger.generationResult(generationId, result);
	},
	onGenerationError: (generationId, error) => {
		logger.generationError(generationId, error);
	},

	callbacks: [maximTracer],
});
const query = "What's the sum of 3 and 2?";
// Optional step to set input of the trace
trace.input = query
const result = await llm.invoke(query);
