I get AttributeError: 'NoneType' object has no attribute 'promotePrefixes' when i try to establish session. I am using python3.7. any help would be greatly appreciated.

from suds.client import Client
client = Client('https://eicu-dev2.fa.em2.oraclecloud.com/analytics-ws/saw.dll/wsdl/v7')
sessionid = client.service['SAWSessionService'].logon('weblogic','Password01')
Traceback (most recent call last):

While using the below lines, I'm unable to get the result set and the query executed :

data=client.service['ReportEditingService'].applyReportDefaults('/shared/DAO - CCR/Task Details',sessionid)
print(data)
x=client.service['ReportEditingService'].generateReportSQL('/shared/DAO - CCR/Task Details',sessionid)
print(x)
