unable to update tagged vlan using update()

[HarishankarYellapragada]

Unable to update using update. Manually updated MG interface. So, I can see that

interface = nb.dcim.interfaces.get(device=device.name, name="GigabitEthernet1/50")
print("Interface name:", interface.name)
print("Interface tagged vlans:", interface.tagged_vlans)
vlan_obj = nb.ipam.vlans.get(vid = 9, group_id=3)
print("VLAN name:",vlan_obj.name, vlan_obj.vid , "| id: ",vlan_obj.id)
print("vlan id:", vlan_obj.id)
vlan_obj.update({'tagged_vlans': [27]})   //Used a different Vlan id manually 
print("tagged_vlans:", interface.tagged_vlans)

output:

Device name: switch-A
Interface name: GigabitEthernet1/50
Interface tagged vlans: [MG]
VLAN name: Inside 9 | id: 27
vlan id: 27
tagged_vlans: [MG]

You code doesn't make any sense: You are calling .update() on a VLAN object, but there is no tagged_vlans attribute in a VLAN object:

>>> vlan = netbox.ipam.vlans.get(4)
>>> vlan
TestVLAN2
>>> vlan.tagged_vlans
Traceback (most recent call last):

This works as expected:

>>> interface = netbox.dcim.interfaces.get(device="Test", name="eth0")
>>> interface.tagged_vlans
[TestVLAN2]
>>> interface.update({"tagged_vlans":[5,6]})
True
>>> interface = netbox.dcim.interfaces.get(device="Test", name="eth0")
>>> interface.tagged_vlans
[TestVLAN3, TestVLAN4]
>>>
