Issues when using http proxy (nginx)

[smbambling]

I'm attempting to get a proxy setup to allow additional servers to send requests over a standard port.

I'm using Ngninx and have tried to setup a proxy_pass with both / and setting a server.contextPath= in application.properties file.

I was setting

application.properties=/gulp

and my proxy pass looks like

  location /gulp {
    proxy_pass http://localhost:8282/gulp;
  }

The error I am getting is

2018-02-10 08:17:26.589  WARN 5526 --- [nio-8282-exec-9] .w.s.m.s.DefaultHandlerExceptionResolver : Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: void com.codenameart.rocketmerger.Webhook.process(java.util.List<com.codenameart.rocketmerger.Message>)

Any suggestions or have you gotten this to work ??
