SNMP, Timeticks, Regex

Hello, I’m having trouble using a regex template to extract a number from a string from an SNMP sensor. The SNMP string is:
"Timeticks: (60080629) 6 days, 22:53:26.29"

The homeassistant sensor doesn’t work, and in the logs:
SNMP error: noSuchName
(other snmp sesnors that return a numeric value are fine)

I’m hoping this is becuase its a string and not numeric?

I’m trying to use a regex template to get the number between paranthesis.
I’ve tried:

{{"Timeticks: (60080629) 6 days, 22:53:26.29" | regex_search('\(([^)]+)\)') }}

But this simply evaluates to True since the string includes parenthesis.

How about :

{{'Timeticks: (60080629) 6 days, 22:53:26.29'.split()[1][1:-1] }}

Should return the number as a string. With a | int on the end should return an integer number.
