How do I add Bearer Token in RSocket client in Spring Boot JAVA

[shivangivar]

I am creating an RSocket Client in Spring Boot using Java. I think there is an issue in adding bearer token from the client end.

Please help me in this.

This is my client code

                        Flux<RSocket> clientRSocket = RSocketConnector.create()
					.metadataMimeType(WellKnownMimeType.MESSAGE_RSOCKET_COMPOSITE_METADATA.getString())
					.dataMimeType(WellKnownMimeType.APPLICATION_JSON.getString())
					.keepAlive(Duration.ofMinutes(10), Duration.ofMinutes(10)).payloadDecoder(PayloadDecoder.ZERO_COPY)
					.connect(transport).flux();
			CompositeByteBuf metadata = ByteBufAllocator.DEFAULT.compositeBuffer();

			RoutingMetadata routingMetadata = TaggingMetadataCodec.createRoutingMetadata(ByteBufAllocator.DEFAULT,
					List.of("/test"));

			ByteBuf simpleAuthentication = AuthMetadataCodec.encodeBearerMetadata(ByteBufAllocator.DEFAULT,
					TenantContext.getCurrentToken().toCharArray());

			CompositeMetadataCodec.encodeAndAddMetadata(metadata, ByteBufAllocator.DEFAULT,
					WellKnownMimeType.MESSAGE_RSOCKET_ROUTING, routingMetadata.getContent());

			CompositeMetadataCodec..encodeAndAddMetadata(metadata, ByteBufAllocator.DEFAULT,
					WellKnownMimeType.MESSAGE_RSOCKET_AUTHENTICATION, simpleAuthentication.asByteBuf());

			clientRSocket.subscribe(rsoc -> {

				Disposable requestStream = rsoc.requestStream(DefaultPayload.create(data, metadata))
						.subscribeOn(Schedulers.newBoundedElastic(1, 100, UUID.randomUUID().toString())).map(mapper -> {
							return mapper.getDataUtf8();
						}).subscribe();
			});

Exception coming from server side
