Activity Monitoring: empty response from backend

See original GitHub issue

This is a…


[ ] Feature request
[x] Regression (a behavior that used to work and stopped working in a new release)
[ ] Bug report  
[ ] Documentation issue or request

The problem

I’ve tried to rerun the soak test scenario on today’s tag 1.4.1-20180605. However, I can’t see any Activity displayed on a page. Backend’s response is empty, even for the straight request to server.

Expected behavior

Activities over time are visibile
