Don't show logs

Hi, I installed this cli and It's not returning logs when I do `awslogs get stream`.
It's not giving any error, It just return nothing.

`awslogs groups` works correctly showing all groups, but when I use `awslogs streams` It don't return all streams also.

Is there something I'm missing? I didn't configure anything, just expected It to work with aws cli credentials.

Aws cli returns cloudwatch log without problem, so I don't think It's a permissions problem.

Start by reproducing the empty output from the `awslogs get stream` and `awslogs streams` entry points using the same AWS CLI credentials, then compare their results with the working AWS CLI command. Done means the commands return the expected streams and logs, or report a clear actionable error when they cannot.
