Tracker Domain Error after update to 4.9

Most of the time, when such kind of error occurs (missing index or table column), the source of the problem is an unfinished update…
Have a look at:

Mysqli prepare error: Unknown column 'login' in 'where clause'

Thanks everyone for your help. I was able to fix this issue yesterday by running the core update command (sudo php /var/www/html/matomodir/console core:update). @Naser_Aslam I believe there were some database changes that the update fixed. Thank you.
