Hi

I encounter a problem. I would like to update a VLAN and I have this error :

2020-07-16 11:17:42       meraki:    DEBUG > {'tags': ['VLANs'], 'operation': 'updateNetworkVlan', 'method': 'PUT', 'url': '/networks/L_TESTTESTTESTTEST/vlans/610', 'json': {'subnet': '10.240.14.0/25', 'applianceIp': '10.240.14.1', 'fixedIpAssignments': {'aa:aa:aa:aa:aa:aa': {'ip': '10.240.14.40', 'name': 'PPTTEST'}}}}
2020-07-16 11:17:42 urllib3.connectionpool:    DEBUG > https://api-mp.meraki.com:443 "PUT /api/v0/networks/L_TESTTESTTESTTEST/vlans/610 HTTP/1.1" 400 None
2020-07-16 11:17:42       meraki:    ERROR > VLANs, updateNetworkVlan - 400 Bad Request, {'errors': ['Subnet and appliance IP cannot be blank.']}

Any idea why ?

thanks

Does the device have VLANs enabled?

Yes, It's a network bound to a template

I think I see one too many opening braces { in the DEBUG output. If that's the case, it would confuse the interpreter about where to look for the subnet/applianceIp params.

For anyone interested in the answer, and who stumbles across this thread like I did when trying to fix the same problem....

I can replicate this error message when I try to update a templated networks IP addresses to IP addresses that already exist on another network within the organisation. 

So the fix is to try updating the templated network to a different set of IPs.....or delete the conflicting subnet on the other network.

Seems like the error message could be more clear, then. You can ask Support to improve that!
