Meraki rest API doesnt accept None as an argument Python (probably noob question)

Hello my Meraki friends,

 

This is probably a noob question. I am trying to programmatically edit a VLAN by using the rest API with Python, however I ran into some troubles.

 

While sending the following json using using requests.put: https://nxxx.meraki.com/api/v0/devices/XXXX-XXXX-XXXX/switchPorts/[portnumber]

 

  Name Value Type

 'accessPolicyNumber'NoneNoneType
 'allowedVlans''all'str
 'enabled'Truebool
 'isolationEnabled'Falsebool
 'linkNegotiation''Auto negotiate'str
 'macWhitelist'NoneNoneType
 'name'NoneNoneType
 'number'10int
 'poeEnabled'Truebool
 'portScheduleId'NoneNoneType
 'rstpEnabled'Truebool
 'stickyMacWhitelist'NoneNoneType
 'stickyMacWhitelistLimit'0int
 'stpGuard''disabled'str
 'tags'NoneNoneType
 'type''trunk'str
 'udld''Alert only'str
 'vlan'2int
 'voiceVlan'NoneNoneType
 __len__19int

 

I get the following response: 

 

'errors': ['Cannot set whitelist on a trunk port', 'Invalid MAC whitelist. To disable MAC whitelist, set accessPolicyNumber to null.']

 

If you take a look at the first entry of the table above, 'accessPolicyNumber' is indeed filled with a NoneType thing, which is the python equivalent to a null character (right?). Setting 'stickyMacWhitelistLimit' to None is also not an option, since it has to be an integer, while strangely enough if i use get, 'stickyMacWhitelistLimit' is filled with a null character. (which was my motivation to put 0 there in the first place, leading to this).

 

API command documentation I used is this.

 

Thanks for your time!

Kind of a big deal

None is null, yes.

 

That looks like you're trying to use Update Device Switch Port?

 

What happens when you leave the items with value None out? I ran into this with... I forget the call... a while ago. It may have been this one. The GET request returns None options that'll make it unhappy if you include them with a PUT.

When I leave them out it works!

 

From my understanding I'd had to send the entire thing. So what I tried to do is do a get request on the port, alter the JSON response to the VLAN I want, and send the edited response back. Seems I can send any amount of key value pairs I want.

 

Although, it also seems that sending a wholly filled JSON thing with all the values does make the system go places.

Finally got a chance to dig in my scripts, and it was this call.

 

This is probably ugly as heck, but my apparent solution from October:

 

for port in switchportsList:
    switchNum = port['number']
    empties = []
    for key, value in port.items():
        if value == None:
            empties.append(key)
    for item in empties:
        try:
            port.pop(item)
        except:
            print(f"Couldn't pop {item}")
    putSwitchport(arg_apikey, arg_serial, port, switchNum, shard)
