import module-type from YAML

Expected Behavior

create a module-type with mapping

Observed Behavior

fail with error
<class 'dcim.models.device_component_templates.RearPortTemplate.MultipleObjectsReturned'>

get() returned more than one RearPortTemplate -- it returned more than 20!

Python version: 3.12.3
NetBox version: 4.5.4-Docker-4.0.1
Plugins: None installed

If I try to import module without {module} placeholder it work correctly
