Hi,
Edit the following url:
https://mysinstance.service-now.com/cmdb_ci_list.do?JSONv2&sysparm_query=sys_created_on>=2000-01-01+00:00:00^ORDERBYsys_created_on&sysparm_record_count=50
mysinstance.service-now.com with your service now instance name
cmdb_ci_list with the service now table you are trying to query
2000-01-01 with the actual date you want to query from
and paste it in your browser. You will be prompted to login, so make sure you do with the same username password you use in the Add-on setup.
Check the results for the following:
1- Do you get the historical data you expected to have?
2- Do you get sys_updated_on field returned in each event?
If not, this is a permission issue.
