Invalid protocol revision 'null' specified for managerID = ESP_XXX_7500. Using default of 2

[Desiree Anson]

My agents are active, they're listed inactive, in the Desktop client admin screen.  I see the following line in the defaultlog_agent.log file:

10/28/2020 15:17:30.793-0400 1 main.MainThread.CybCommunicationManager.a[:561] - Invalid protocol revision 'null' specified for managerID = ESP_XXX_7500. Using default of 2

Does anyone know what else I might need to do to fix this? 

Thanks.

Hi,
When you installed the agent, did you choose AE mode or the 2nd mode (ESP/DE)?
Also, what is the version of agent?

Hi Nitin,
Unfortunately I can't remember & I don't see an indication of mode in the summary that was displayed (I copied and saved it for reference) at the end prior to hitting the Install button.  Is there a way I can tell this from the installation?  If not, I can go through it again to figure out what I did.
Thanks,
Des

I realize now what you're asking.  I installed the addons for the database to the ESPAgent that gets installed with the server software.  Not the separate system agent installation.  So I used the plugin installer under the ESPAgent folder to install the database addon (cfg file).
