Error return on modifying pool member property with python script

Hi,

 

I have tried to use python script to modify the 'ratio' field for the member of pool and I always get following message in spite of using 'put' or 'patch' method:

 

{u'errorStack': [], u'message': u'invalid property value "state":"up"', u'code': 400, u'apiError': 26214401}

 

If using iControl REST curl command, the value of 'ratio' can be changed without problem.

 

Anyone can help me to figure out ?

 

Thanks,

 

Roger
