SNMP Set Issue

[Alestrio]

Hello,
I'm trying an SNMP set based on your lib.

Here's my code :

    def set_interface_vlan(self, interface_id, vlan_id):
        self.set(self.OIDS['interfaces']['sets']['vlan']+f'.{interface_id}', vlan_id)

And here's the error :

ERROR:    Exception in ASGI application

What's the cause of this adn how to fix it ?

Thanks,

Seems to be a problem caused because no MIB is imported and looked up. Should consider making a cast function
