OMS responded illegally [ERROR- Failed to Update Target Type Metadata] in 13c R2

I want to discuss about this OMS error coming from the agent’s heartbeat status. The agent shows with an unreachable status but is actually up and running.

Agent is Running and Ready
In this case the agent is not able to upload the metadata because is different in the OMS.
This is mainly due to a patch in the agent side that is missing in the OMS. By mistake I applied the latest bundle patch to the agent before applying it to the OMS.
Just another proof that any patches have to be installed to the OMS first then the agents.
