Discovery Sensor error after Quebec Upgrade: InternalError: Can't find method com.snc.discovery.logging.DeviceHistory.state(string,string,undefined,string,undefined). (sys_script_include.d22e7bdbc0a8016500a18e024bfc9aa3.script; line 4)DescriptionVarious Discovery Sensors may fail with the following error, after an update to Quebec: InternalError: Can't find method com.snc.discovery.logging.DeviceHistory.state(string,string,undefined,string,undefined). (sys_script_include.d22e7bdbc0a8016500a18e024bfc9aa3.script; line 4) In the case of a Interactive Probe Shell sensor, the full errors looks like this, however other sensors' errors will be slightly different: InternalError: Can't find method com.snc.discovery.logging.DeviceHistory.state(string,string,undefined,string,undefined).

This would also be a good time to check other skipped upgrades in your Upgrade History, particularly for patterns, probes, sensors and script includes.
