Not able to set secrets value using fab set --environment

[amit1411]

I need to set values for a secret thru environment using fab --environment set but not able to do so as it gives formatting error. Is it possible to do it via command line?
secrets:
- name: "secret_name"
value:
variable1:
variable2:
I tried using below command
fab set --environment prod --subcomponent my_sub_component secrets.name=secret_name secrets.value.variable1="some_value" secrets.value.variable2="some_value_2"
