Sometimes it happened for me when session2 was not yet ready, and I fixed this by adding a small workaround: "session:sleep(500);"
Please see below, and reply back if it works for you.

--------------------
session:answer()
session2 = freeswitch.Session(callstring)

session:sleep(500);

if (session2:ready()) then
   freeswitch.bridge(session, session2)
end
--------------------
