Hi,  
i ve setup an playbook with cli\_command  
I ve a static inventory

> 192.168.200.159 ansible\_network\_os=ios ansible\_ssh\_user=user ansible\_connection=network\_cli

everything is working as expected, and executed on a cisco switch

now i ve changed the inventory to dynamic netbox inventory

> * * *
> 
> plugin: netbox.netbox.nb\_inventory  
> validate\_certs: False  
> config\_context: True  
> compose:  
> ansible\_network\_os: ios  
> ansible\_ssh\_user: user  
> ansible\_connection: network\_cli

now i got this error when it tries to connect

> “msg”: “Connection type ssh is not valid for this module”

it looks like that my variables are not used in dynamic invnetory  
I ve tried to add the variables to ansible.cfg  
and I ve tried to add the variables to netbox context

Maybe someone can point me the right direction

thanks

Using compose with strings needs a little bit more than just treating it as a regular ansible variable

As an example try using:

```auto
compose:
     ansible_network_os: "'ios'" 

```

You’ll need to do this for all of your compose vars.
