Render config Netbox v3.6.4

Netbox v3.6.4

I have the following jinja2 template but it is not rendering, I do not get the hostname and I get the following error in 'interfaces'

Config Template

hostname {{ device.name }}

{% for interface in device.interfaces.all() %}
interface {{ interface.name }}
switchport mode access
switchport access vlan {{ interface.untagged_vlan.vid }}
{% endfor %}

Error

That template works for me in Netbox 3.7.8 / Python 3.8.10.

Is that the entire template, or is there some other part before this? Somehow "device" seems to be set to a string, not an object.

Can you replicate this at demo.netbox.dev ?

That's all the template I'm using, I replicated it in demo.netbox.dev and it works for me.

Do you know by chance why 'device' is configured as a string and not an object, is it a version problem?

I don't know, but you should in any case upgrade to v3.6.9 to eliminate that possibility.

Have you got any plugins installed? Badly-behaved ones might mess with Netbox internals. Try disabling them temporarily.
