Python version

Steps to Reproduce

Given data:
site named import-test
rack named import-rack in site import-test
device role named import-role
manufacturer named import-manufacturer
device-type named import-device with manufacturer of import-manufacturer

CSV data:

name,role,serial,description,manufacturer,device_type,airflow,status,site,location,rack,position,face
,import-role,3412341,,import-manufacturer,import-device,front-to-rear,active,import-test,,import-rack,,
,import-role,kljadf123,,import-manufacturer,import-device,front-to-rear,active,import-test,,import-rack,,

Steps to replicate import failure:
Devices -> Devices -> Import.
Paste data to direct import text box.
Submit.

Expected Behavior

Devices from csv would be imported.

Observed Behavior

Removing the location field (and leaving other empty fields) successfully imports devices.

New CSV:

name,role,serial,description,manufacturer,device_type,airflow,status,site,rack,position,face
,import-role,3412341,,import-manufacturer,import-device,front-to-rear,active,import-test,import-rack,,
,import-role,kljadf123,,import-manufacturer,import-device,front-to-rear,active,import-test,import-rack,,

Devices import as expected.
