nios_inventory doesn't have a handle_exception method

[evilhamsterman]

The nios_inventory plugin doesn't have a handle_exception plugin so if there's a problem instead of a useful message you get

Failed to parse /inventories/infoblox.yml with ansible_collections.infoblox.nios_modules.plugins.inventory.nios_inventory plugin: 'Connector' object has no attribute 'handle_exception'

which doesn't tell you anything about what's wrong whether it's a wrong username and password, the host is unreachable, etc.
