AWS ECS describe-task-definition doesn't return EFS file system specification

Question

I tried with

aws ecs describe-task-definition --task-definition task1

but only get the volume names

...,
"volumes": [{
     "name": "test1"
}], ... 

According to spec I should receive an efsVolumeConfiguration object inside each volume, too. Does anyone know why I can't see the information or how I otherwise can retrieve it? Thanks in advance!

Answer 1

Found the issue.

Had to upgrade my aws cli to version aws-cli/2.0.58, now it get the efsVolumeConfiguration.
