Traverse Json objects inside Arrays in Rego - json

Question

I want to get the value of client_broker key and check if it is TLS or not ,if TLS the rego should pass else it will fail,but i am not able to traverse the nested json within the array element,tried using walk but not working,,,need help :(
Was trying using the below code but did not worked
deny{
r := tfplan.resource_changes[_]
r.type == "aws_msk_cluster"
name := r.change.after.encryption_info[_]
#val := walk(name,["encryption_in_transit"],"TLS")
print(name)
#print(val)
contains(name,"TLS")
}

"create"
],

Answer 1

Finally solved the issue by the below line of code
is_encryption_in_transit{
r := tfplan.resource_changes[_]
r.type == "aws_msk_cluster"
name := r.change.after.encryption_info[_]
[path,val] := walk(name.encryption_in_transit)
protocol = val["client_broker"]
cluster_encryption = val["in_cluster"]
protocol == "TLS"
cluster_encryption == true
}
