[Bug]: SQL Param {{null}} getting passed to postgres as 'null'

Is there an existing issue for this?

• [x] I have searched the existing issues

Current Behavior

I have a function call like

SELECT * FROM func_network___get_network_activity_rollup( p_activity_filter => {{ ui_trackerFilter.value || null }}::varchar );

ui_trackerFilter is a select component. If it is empty the JS Snipped should reduce to {{null}}, but it gets passed to postgres as the string 'null'

Expected Behavior

I would assume a null JS value would get passed to postgres as a NULL

Steps to reproduce

See Above

Environment

2.7.4
