ValueError: Ambiguous content type back mapping dcim.location

Steps to Reproduce

1. Dump netbox data with command python3 ./manage.py dumpdata -v 3 --traceback --format=json --exclude extras.ObjectChange --exclude extras.report --exclude extras.script --exclude django_rq --output=/tmp/netbox_data.json
2. install nautobot-netbox-importer with pip3 install nautobot-netbox-importer as user nautobot from $NAUTOBOT_HOME
3. Run import command nautobot-server import_netbox --print-summary --dry-run --update-paths --bypass-data-validation --sitegroup-parent-always-region /tmp/netbox_data.json

I did notice that the options I have don't match the docs. There's no --field-mapping option, and --summary seems to have changed to --print-summary also --help didn't work but I put those down to documentation not having quite caught up with the updates.

Running nautobot-server import_netbox with no options gives me:

                                     json_file

I note on the app page in Nautobot's Web UI it says "Data importer from NetBox 2.10.x to Nautobot."

Is this plugin intended to work with Netbox 3.7.x?

Thanks.

yes. I guess the Nautobot0s Web UI is still referring to the previous version. Could you share the exact reference to fix it?

I had to add --exclude extras.configcontext flag in netbox dumpdata command to workaround this.
