1. The core-data config is required for device-sdk-go https://github.com/edgexfoundry/device-sdk-go/blob/main/internal/clients/init.go#L58

2. And we just upgrade the lib from v2.1 to v2.2, it's the latest changes from the go-mod-bootstrap, the BootstrapHandler keeps trying to get the service endpoint.
   https://github.com/edgexfoundry/go-mod-bootstrap/pull/305/files

func (cb *ClientsBootstrap) getClientUrl(serviceKey string, defaultUrl string, startupTimer startup.Timer, lc logger.LoggingClient) (string, error) {
	if cb.registry == nil {
		lc.Infof("Using configuration for URL for '%s': %s", serviceKey, defaultUrl)
		return defaultUrl, nil
	}

	var err error
	var endpoint types.ServiceEndpoint

	for startupTimer.HasNotElapsed() {
		endpoint, err = cb.registry.GetServiceEndpoint(serviceKey)
		if err == nil {
			break
		}

		lc.Warnf("unable to Get service endpoint for '%s': %s. retrying...", serviceKey, err.Error())
		startupTimer.SleepForInterval()
	}

If Core data is not being used, then it needs to be removed from the Clients section of the configuration.

Per the Registry ADR, bootstrap now uses the registry to get the endpoint of all clients.

@weichou1229, Since Core Data is now optional, this check in the SDK should be removed.
