Python api script mxfirewallcontrol.py json format error

[JFarley]

Hey all, absolutely new to API's. I'm trying to use the python script mxfirewallcontrol.py to insert a rule into a network's l3 firewall.

Following the example at create.meraki.io/build/mx-firewall-control-python-script/ for expressing rulesets I've replicated the following:

python mxfirewallcontrol.py -k xxx -o "xxx" -f "type:network,name:xxx" -c insert:2:"{ ""protocol"":""any"", ""srcPort"":""Any"", ""srcCidr"":""Any"", ""destPort"":""Any"", ""destCidr"":""192.168.26.0/24"", ""policy"":""deny"", ""syslogEnabled"":false, ""comment"":""D - All to POS VLAN"" }" -m simulation

and I receive:

@ INFO: Retrieving organization info
@ INFO: Selecting networks and templates according to filters
@ INFO: Simulation mode. Changes will not be saved to cloud
@ ERROR 50: Ruleset to be added must be given in JSON format

I tried replicating the example exactly and editing in my info and it still fails.

Any advice would be appreciated.

My first observation is the -m simulation.  I don't think you are running a real query.  Nextly you may want to look here

In that thread, they were doing a similar function and it discusses the proper syntax and a few nuances.
