Endpoint manager throws "A non-numeric value encountered" upon updating configs, after upgrading to version 16

Prior to upgrading to freepbx version 16 I renewed my subscription for the endpoint manager to ensure it would be compatible.  However, after performing the update (with no known errors) and attempting to generate a new phone configuration file in the endpint manager I get this error.

I've attached the error as an image as I am not seeing a way to export the text of the error.

So I'm not sure if this is a bug but I did follow the provided upgrade instructions, and this module was working prior to upgrading so If it's not a bug I'm not sure how to go about getting support for this paid module.

 Also, the version of my endpoint manager is not listed in this ticket so I chose the closest option, but My version is listed at 16.0.66

Thanks!
