[Freeswitch-users] Trouble Getting session:getVariable("state") in Lua

[Matthew Fong]

I'm having trouble getting the channel variable state in my Lua ivr example.
I have tried both

session:getVariable("state")
session:getVariable("Channel-State")
session:getVariable("answer_state")
session:getVariable("Answer-State")

but lua reports nil for all attempts

I did a uuid_dump and it appears normal....and both Channel-State and
Answer-State Variables are present...does anyone know why my Lua IVR can not
get these channel variables? Thanks
