Not able to send client Request through RSC cli

I am using a simple rSocket server to handle the client request. Using RSC cli to send Client request.

java -jar rsc.jar --debug --request --data "{\"message\":\"HiSourav\"}" --route request-response tcp://localhost:7000

Above is the command i am using to send the request and getting the below mentioned error.

Error: Could not resolve method parameter at index 0 in reactor.core.publisher.Mono<com.example.RsocketTestWithClient.entity.Message> com.example.RsocketTestWithClient.RsocketTestWithClientApplication.requestResponse(com.example.RsocketTestWithClient.entity.Message): Failed to read HTTP message; nested exception is org.springframework.core.codec.DecodingException: JSON decoding error: Unexpected character ('m' (code 109)): was expecting double-quote to start field name; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('m' (code 109)): was expecting double-quote to start field name

Let me know any suggestions you have.

Solution

  • Your error suggests a problem in the client,

    Unexpected character ('m' (code 109)): was expecting double-quote to start field name at [Source: (io.netty.buffer.ByteBufInputStream); line: 1, column: 3]

    So I'd try to confirm you are sending the right content.

    Use the --debug (or --wiretap) output to confirm that the data is correctly sent by the client. If you have done that e.g.

    $ rsc --request --data "{\"message\":\"HiSourav\"}" --debug tcp://localhost:9000

Use --stacktrace option for details.

    Then you can confirm it's a server problem and you should debug why the server is breaking here.
