Adding Windows or Linux servers to protection on a Rapid Recovery or AppAssure Core results in the error message:
Invalid enum value 'SupportsStreamableDisksMetadata' cannot be deserialized into type 'Replay.Common.Contracts.Metadata.AgentFeatures'. Ensure that the necessary enum values are present and are marked with EnumMemberAttribute attribute if the type has DataContractAttribute attribute.
To resolve this issue, completely uninstall the agent software from the affected server and install a compatible release. Download for AppAssure and Rapid Recovery can be found in the Quest downloads page located at our Download Software" page.
*Note: If the affected agent is a custom Linux agent, make sure you also install the appropriate core patch if the Linux agent requires it.
