Create an CFEngine agent with a key containing DSC, for ex. one with the following content for 'agentName' attribute:

{"agentType":"cfengine-community","version":"4.2.0.beta2-1.EL.7","securityToken":{"value":"-----BEGIN RSA PUBLIC KEY-----\nMIIBCgKCAQEAyXUx8lDOtFca/aDLME1EAtvu9NhLWR74Q5jxnyUii8JujMKqv7Xk\nnsTAa2ivfopbzhNRMLsUPRkYSJEi3w0gBe2iQ9S39oXiiUUTozbV2GpOXQNLOERy\nWMol3ozsJXOuA5/2FtkvW3UxxMCfq2OPEF8Qqg3vfzBRZga5QtKGmSHMpFEDbOxn\nOUzSzN+MFSv9EGY18X61K2/+eicwCvAX9bhLapJcZf/4aIitsYKSsnQEmmR3Ae78\n6SMhDCtvJCjnt/6Pw2MI6F/0tC3xi1dQyXVcGlM8AoPKvHLv7Xmp8wrr0WEyuJlF\nYE6NrACm2kLui+FWDn0xhfm6PXGJYdSCqwIDAQAB\n-----END RSA PUBLIC KEY-----","type":"publicKey"}}

That agent will be found when looking for "agent -> DSC"

{"select":"nodeAndPolicyServer","composition":"And","where":[{"objectType":"node","attribute":"agentName","comparator":"eq","value":"dsc"}]}

Obviously, the search need to only look for the value for key agentType. This is certainly a problem with the JSON search, so referencing #10599 and more specially #10570
