Hi  djordje.golubovic@,
Based on the stack trace, this is the problem with the page content has changed, so the test logic no longer apply. We would need to modify the test logic to match the new page content. 

For example:
[ RUN      ] google_calendar
(WARNING) 2018-03-20 16:40:39,274 action_runner.__exit__:822  Exception was raised in the with statement block, the end of interaction record is not marked.
(WARNING) 2018-03-20 16:40:39,274 shared_page_state.DumpStateUponFailure:138  Taking screenshots upon failures disabled.

[  FAILED  ] google_calendar (29166 ms)


This tells that there is no element that matche selector '#scrolltimedeventswk'

This is not a defect of record_wpr, so close the bug.

Hi nednguyen,
thanks for clarification!

Could you suggest where would be the best place to post issues similar to this (test logic needing update), as there may be a few more in tests we are running?

djordje.golubovic@mips.com: there is no general place to post issues (test logic needing update) that I know of. Usually engineer working on updating the pages make the change themselves. If you run this live instead of with recording, it's on your own to figure out which test logic need to be updated.
