[karatelabs/karate] Karate framework : Multi threaded access requested by thread Thread[nioEventLoopGroup-2-1,10,main] but is not allowed for language(s) js thrown when I use handle for the websocket

[sofianeAmarouche]

Please help if you can , I have the following test

Feature: websocket test operation

@websocket_test Scenario Outline: testing websockets

• def req = read('classpath:testData/RequestData/')
• string req = req
• def expected = read('classpath:testData/ExpectedResponseData/')
• def handler = function(msg){return msg.startsWith('{') && !msg.includes('context')}

  demoBaseUrl is a wss address and is defined in the config file

• def socket = karate.webSocket(demoBaseUrl, handler)
• socket.send(req)
• listen 5000
• print 'listen result is : ', listenResult
• json result = listenResult
• match listenResult == expected Examples: | requestJson | expectedJson | | requestTestData.json | responseTestData.json |

I noticed that when i use the handle within my scenario I get as follow

• def handler = function(msg){return msg.startsWith('{') && !msg.includes('context')}
• def socket = karate.webSocket(demoBaseUrl, handler)
• socket.send(req) The following error is given Multi threaded access requested by thread Thread[nioEventLoopGroup-2-1,10,main] but is not allowed for language(s) js

I tried to use warp the handle as follow but the error still persist

• def socket = karate.webSocket(demoBaseUrl, karate.toJava(handler))
• socket.send(req)

However when I dont include the handle like the following, the same error is not thrown

• def socket = karate.webSocket(demoBaseUrl, handler)
• socket.send(req)

In my case I have the use the handle to return the desired response body and I tried to create a custom java method for the handler but it doesnt work it is giving the following error

• def javaHandle = runUtility.java_Handle(msg) js failed:

  01: runUtility.java_Handle(msg) <<<< org.graalvm.polyglot.PolyglotException: ReferenceError: "msg" is not defined

• .:program(Unnamed:1)

Below is my test Background:

• def utility = Java.type('javaUtilities.javaKarate')
• def runUtility = new utility()
• def javaHandle = runUtility.java_handle() @websocket_test Scenario Outline: testing websockets
  • def req = read('classpath:testData/RequestData/')
  • string req = req
  • def expected = read('classpath:testData/ExpectedResponseData/')

    demoBaseUrl is a wss address and is defined in the config file

  • def socket = karate.webSocket(demoBaseUrl, javaHandle )

    * def socket = karate.webSocket(demoBaseUrl)

  • socket.send(req)
  • listen 5000
  • print 'listen result is : ', listenResult
  • json result = listenResult
  • match listenResult == expected Examples: | requestJson | expectedJson | | requestTestData.json | responseTestData.json |

Below is is my java_handle() method in java

package javaUtilities;

public class javaKarate { public static Boolean java_handle(String msg){ return (msg.startsWith("{") && !msg.contains("context"));

}

}

I'm not sure what else I should do, not sure if there is an alternative the handle . Please help
