Permission denied trying to move file for loading test and prod properties - AWS ebextensions

I read a lot of other answers but with no success, my goal is to load different properties reading environment name.

I have this structure

.ebextensions/properties/test_properties
.ebextensions/properties/prod_properties

and I would move and rename one of these file in .ebextensions to be load after changing extension in ".config"

I have this 00_environment.config in .ebextensions with

option_settings:
  aws:elasticbeanstalk:application:environment:
    MYENV: '`{ "Ref" : "AWSEBEnvironmentName" }`'  # get the current environment name

files:
  ".ebextensions/move.sh":
    mode: "000755"
    owner: root
    group: root

container_commands:
  01_mycommand:
    command: .ebextensions/move.sh
    test: '[[ $MYENV = "env-test" ]]'

Move.sh (into folder .ebextensions)

mv properties/test_properties test_properties.config

Logs in eb-activity.log
