What is QVX_UNEXPECTED_END_OF_DATA? One of our Client is facing this problem, when they load data from Oracle.Please find the Snap Shots Attached
Operations Monitor and License Monitor apps use the Qlik REST Connector to fetch data. The connector requires Windows Authentication to be successful in fetching data. This issue occurs when no virtual proxy in the Qlik Sense deployment utilizes Windows authentication.The issue can be resolved by enabling Windows Authentication for example by adding a secondary virtual proxy using Windows authentication.
I faced this error a few days ago.
I tried to load data from a clickhouse database. In my case the solution which fixed this problem was to use a odbc conenction instead of oledb. Since then the problem doesn't occur again.
