Hello,
could you explain more deeply how you did this? Maybe you can give the attachments to let me understand and try to reproduce this situation?

I have created my own entity for reviews and I want to see them in the calendar view. Any Reviews will not be displayed in the calendar view if I add a users relationship (I get a bad server response) and no events will be display at all. If I remove users from the review then the review will be seen in the calendar the same as any other events. I have not modified the users form - it is pretty much 'out of the box. I am unsure as to why adding a users relationship causes the calendar form to crash. Here is the espo error log file -

The error log displays
[2019-02-25 16:23:18] Espo.ERROR: API [GET]:/Activities, Params:Array ( ) , InputData: - SQLSTATE[42S22]: Column not found: 1054 Unknown column 'usersMiddle.user_id' in 'where clause' [] []
