Description:

Parameter 0 of method websocketRoutingFilter in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.web.reactive.socket.client.WebSocketClient' that could not be found.

The following candidates were found but could not be injected:
	- Bean method 'reactorNettyWebSocketClient' in 'GatewayAutoConfiguration.NettyConfiguration' not loaded because @ConditionalOnClass did not find required class 'reactor.ipc.netty.http.client.HttpClient'
