Workaround

There are no workarounds for this issue, however, note that this only affects platforms where model-driven telemetry is enabled and in-use by DNAC or Prime. To see if your device has telemetry enabled, you need to look for "netconf-yang" in the configuration. To see if the telemetry on your device is in use by DNAC or Prime, you need to look for a "protocol" of "cloud-native", "native-tls", "native", "cntp-tls" or "cntp-tcp" in the telemetry section of your configuration.
