REST API scripts are not working-automation not working after upgrade to 17.x

Hi Team, 

Some of the methods are not working in our scripts after we upgraded to 16.x and or 17.x below are the details.

Thanks in Advance for any help on this.

We have upgraded our LB from 15.1.8 to 17.1.0.1 and also on 16.1.4.3 on both versions we are seeing below behavior.

We have REST API and python scripting to enable/disable pool members which is not working after the upgrade. Below are few logs which we captured during

our debug on device in question. need to know why does it shows exception and also fix needed here.

Note : the REST API and Python script works fine on 15.1.8 without any issues.
