Parse json output for a specific key in Ansible variable

I have a specific JSON output shown below using dummy data loaded inside a variable in Ansible:

"nodes":
"100.29.28.153":
"agent": "UP",
"db": "UP",
"info": " ",
"type": "Master",
"xlog": "6C\/2400A990",
"xloginfo": ""
,
"100.29.28.154":
"agent": "UP",
"db": "UP",
"info": " ",
"type": "Standby",
"xlog": "6C\/2400A990",
"xloginfo": ""
,
"100.29.28.155":
"agent": "UP",
"db": "N\/A",
"info": " ",
"type": "Witness"
,
"100.29.28.163":
"agent": "UP",
"db": "UP",
"info": " ",
"type": "Standby",
"xlog": "6C\/2400A990",
"xloginfo": ""
,
"100.29.28.165":
"agent": "UP",
"db": "N\/A",
"info": " ",
"type": "Witness"




How do I parse this in Ansible and register a new variable using the type=Master as a means of selecting that nodes IP address? In the example above, the new Ansible variable should be set to "100.29.28.153" since that IP address is the Master node

For example by combining dict2items filter with JMESPath:

dict2items

- set_fact:
my_var: " json_query('[?value.type==`Master`] "
