This seems to come down to the fact that this field is optional:

netbox/netbox/extras/forms/bulk_import.py

Lines 245 to 257 in 32ea174

	class TagImportForm(CSVModelForm):
	slug = SlugField()
	weight = forms.IntegerField(
	label=_('Weight'),
	required=False
	)
	object_types = CSVMultipleContentTypeField(
	label=_('Object types'),
	queryset=ObjectType.objects.with_feature('tags'),
	help_text=_("One or more assigned object types"),
	required=False,
	)

If omitted, prepare_value tries to call object_type_identifier(value) which assumes value to be a resolved ObjectType but fails when value is null.
