Generally, the above error occurs if you have provided an incorrect join.key/pairing token when you add the JPD under Register platform deployment. If you are using the pairing token for registration and the mission control version used is lower than 4.9.0, you would observe a similar error. In this situation, you must use join.key to add the JPD as a platform deployment, because adding JPD via pairing token is supported in Mission Control version 4.9.0 and above. Please check the Mission Control Release Notes for more information.
