Steps to Reproduce

Create a custom field foo as text with default search matching

assign the custom field to a virtual machine object and set a value to bar

virtualization | interface
ipam | IP address
virtualization | virtual machine

Create a nb inventory like

plugin: netbox.netbox.nb_inventory
api_endpoint: https://netboxexample.com
validate_certs: true
query_filters:
  - cf_foo: bar

Expected Behavior

Result should be ansible inventory contains all virtual machines with the assigned custom field foo and value bar.

Observed Behavior

The filter is not working and i get all devices back.

The API call is working as expected
api/virtualization/virtual-machines/\?limit=0\&cf_foo\=bar\&exclude\=config_context
