Ho can i send custom data with client.captureException()?

CREATE OR REPLACE FUNCTION public.ravenlog(a integer)
    RETURNS integer
    LANGUAGE 'plpythonu'
    COST 100.0
    VOLATILE 
   AS 
 $function$
from raven import Client
client = Client('__DSN__')
try:
 1 / 0
except ZeroDivisionError as err:
 client.captureException()
return a
$function$;

I want to add custom data with client.captureException() like some json data . How can i do so ? Thanks
