Unable to get Members of a list

[vs2ds]

Please let me know if i am using the command wrong. The combinations I have tried.

Username: Bingo
List Name: Poker

The command combinations I tried:

t list members Bingo/Poker
t list members Bingo/Poker -l
t list members @Bingo/Poker -l
t list members Bingo/Poker
t list members -i 1295616516551648162 -l
t list members 1295616516551648162 -i
t list members Bingo/Poker -l
t list members Bingo Poker
t list members @bingo Poker
t list members [Bingo]Poker
t list members [Bingo/]Poker
t list members [@Bingo/]Poker
t list members Bingo/Poker
t list members Bingo\Poker

Mostly the output I got was...
/usr/local/bin/t: execution expired
/usr/local/bin/t: Sorry, that page does not exist.

Let me know its its issue with usage of the internal code.
