    Hi,

    The error is because of too low Prefetch value.

    Please use this SQL to increase your prefetch value to 10 mins:

    ALTER SYSTEM ALTER CONFIGURATION ('dpserver.ini', 'SYSTEM') SET ('framework', 'prefetchTimeout') = '6000' WITH  RECONFIGURE;

    You can also disable the prefetch by running this SQL:

    ALTER SYSTEM ALTER CONFIGURATION ('dpserver.ini', 'SYSTEM') SET ('framework', 'usePrefetch') = 'false' WITH  RECONFIGURE;
