Lost in app traceback after sentry php sdk update

I’ve updated PHP packages

sentry/sentry-symfony from 3.5.3 to 4.0.1
and also updated
sentry/sentry from 2.5.2 to 3.1.5
my sentry server is on premise - version 10.1.0

and I lost in app traceback - the feature where I can see lines of my app where the error failed and also see parameters that where passed to the method/function.

How can I enable it back? What I can do, is downgrade it to the previous version, back this way my app will not stay up to date
