"`error: 'SerialSARA' was not declared in this scope`"

When I try to use the library, in the "NBWebClient" example, I get the same error from the Modem.cpp file.

..\libraries\MKRNB\src\Modem.cpp:383:18: error: 'SerialSARA' was not declared in this scope

exit status 1

Compilation error: exit status 1

This is using the NBWebClient.ino example file, no changes made, and MKRNB version 1.5.1.
