Price Agent Feed has empty result after release or after the priceagentscheduler gets executed

Questions
1

After every release the price agent feed returns empty result.

But when running https:///priceagent.axd/productfeedjson?refresh=true
it generates product feed.

I made sure that scheduled task for priceagentscheduler is set in the config

What could be the issue?

Litium version: 7.6.1

2

Does that log-file says anything related to when the background task is executed?

I can see this bug in release notes that may be related, Bug Details (litium.com)

I dont see anything specific in log relating to backround task.
