Trying to create VIPs via Python and get an error

Here is the snippet of code that is used to create the VIPs on the f5;

 

rv0=revisedServer.replace("dev_","test_vip_")

  print (eachServer[0][3].upper())

  rv1=eachServer[0][3].upper()

  params = {'name': rv0, 'source': "0.0.0.0/0", 'description': "TEST VS",'protocol': rv1,'pool': revisedServer,'profiles': profiles,'partition': 'Common','sourceAddressTranslation': {'type': 'snat'},'vlansEnabled': 'True','vlans': ['/Common/Dev'],'arp':'disabled','icmpecho':'disabled','state':'disabled','port':eachServer[0][1],'tagMode':'none'}

  print (params)

#LETS CREATE VIRTIUAL SERVERS IF THE SERVER ALREADY EXISTS KEEP IT MOVING

  try:

   ltm.virtuals.virtual.create(**params)

  except Exception as e:

   print (e)

 

 

 

When run I get the following error:

 

 

400 Unexpected Error: Bad Request for uri: https://pltbigip01.pexdev.corp:443/mgmt/tm/ltm/virtual/

Text: '{"code":400,"message":"Instance contains a string","errorStack":[],"apiError":1}'

 

Does anyone know why?

       if you reformat your code there to use the codeblock, it'll be helpful. I can take a look a little later tonight to see what's going on. In the meantime, if you're just getting started with f5-common-python, I'd recommend you take a look at bigrest instead, as it is in active development.

    Some feedback on your sample:

    'Protocol' --> Should be:
	'ipProtocol'
 
'vlansEnabled': 'True' --> Should be:
	'vlansEnabled': true
 
 
'icmpecho' --> Should be:
	'icmpEcho'
		BUT
	this is not an attribute on the virtual server, it's on the virtual address (/mgmt/tm/ltm/virtual-address/<ip>), as is the 'arp' attribute
 
'state': 'disabled' --> Should be:
	'enabled': true
		OR
	'disabled': true
 
'port' --> Is included in:
	'destination'
		BUT
	that property is missing, it should include ip:port
 
Make sure profiles is configured appropriately, it is a sub collection
 
'tagMode' is not a property I can find on either virtual server or virtual address, what version are you on?

    If you want to see the properties on a method, you can use the example by hitting https://your.bigip.here/mgmt/tm/ltm/virtual/example. It's 503 lines long or I'd post it here. Hope this helps.
