It's hard to say what might be wrong.  You need to provide more details,
such as what the exact command is you're invoking, and what your
environment looks like.  Use the env(1) command and the AWS online
documentation to ensure you have everything set up correctly; if you
still can't figure it out, send all relevant details to the list.
