Date parameter is throwing an error

Summary: A date value is stored in the screen_entry_value field.

I created two date parameters (p_week_start, p_week_end).

I am trying to use the screen_entry_value in my where condition.

and to_date(peevf.screen_entry_value, 'YYYY-MM-DD HH24:MI:SS') between :p_week_start and :p_week_end

But then I get the below error.

What am I doing wrong?
