Can't change/write MonitoredValue in Limiter

Hello, I'm using a Python library and can't change the monitored value in the Limiter object. When I use Director everything works as expected, maybe I'm doing something wrong?

limiter = GXDLMSLimiter('0.0.17.0.0.255')
reg_obj = GXDLMSRegister('1.0.31.7.0.255')
limiter.monitoredValue= reg_obj
limiter.monitoredAttributeIndex = 2
self.reader.write(limiter,2)

Thanks for the answer.

I read on the forum that the object should be taken from the association and updated my code. But the result remained unchanged, I add the code and log.

limiter = self.reader.client.objects.findByLN(0, "0.0.17.0.0.255")
value = self.reader.client.objects.findByLN(3, "1.0.31.7.0.255")
limiter.monitoredValue = value
limiter.monitoredAttributeIndex = 2

print("==========read===========")
read_mon = self.reader.read(limiter, 2)
print(read_mon)
print("==========write===========")
self.reader.write(limiter, 2)
print("==========read===========")
read_mon = self.reader.read(limiter, 2)
print(read_mon)

From the log
