Groovy validation swaps expected and got when using JSON assert

Question
I have the following testing scenario :
Inbound SFTP -> Mulesoft (SUT) -> Sends message to AMQ
I need to validate if the message send to Anypoint MQ is the same as the test sample

Therefore I wrote a script that looks like this :

.... imports

// Get Response message from context
def responseText = context.getVariable("amqResponseMessage")
def responseType = context.getVariable("amqResponseType")

// Parse message body
def responseJson = new JsonSlurper().parseText(responseText)
def actualMessageBody = responseJson[0].body

// Get Comparable file from filesystem
def filePath = context.getVariable("filePathAmqResponseMessage")
def fileContent = new File(filePath).text

Logger logger = Logger.getLogger("")

// Validate messages
switch (responseType) {
    case "json":
        // Validate JSON
        logger.info("----- actual ----")
        logger.info(actualMessageBody)

        logger.info("----- expected ----")
        logger.info(fileContent)

        JSONAssert.assertEquals(actualMessageBody, fileContent, JSONCompareMode.STRICT)
        break
}

When using this script in other test scenarios it works perfect but it seems that when you have the SFTP -> AMQ the expected and got, are being swapped for some reason :

What I've tried so far
To Debug I added the loggers for actual & expected and there each file is in the proper variable (so not swapped)

Additional information

Maybe update to macOs Sonoma ?

Step for receiving & validating :

 <step then="^ape-shipments-mule4 transforms and forwards the SV033F message with payload (.*) to Anypoint MQ$" parameter-names="outboundAmqRequestMessage">
        <citrus:sleep seconds="1"/>
        
          <!-- Get all messages from AMQ destination -->
          <http:send-request client="amqMessageClient">

                </http:validate>
            </http:body>

            <!-- Extract body into variables for later usage -->
            <http:extract>

        </http:receive-response>

        <!-- "Acknowledge" message and remove from AMQ destination -->
        <http:send-request client="amqMessageClient">

            </http:DELETE>
        </http:send-request>

        <!-- Validate Response message -->
        <citrus:create-variables>

    </step>

[bbortt]

would be worth figuring out if this is still an issue with the latest mileston 2 release, I think?

[JensVanhulstSolita]

@bbortt it's used in company env, we use a parent pom for dependencies and updating to 4.0.0-M2 would mean updating over 100 apps and making sure they work, but I can verify with a dummy project

[christophd]

would be good to have the SFTP steps that extract the variables

[JensVanhulstSolita]

@christophd It isn't going to help in this case. The SFTP message is different from the AMQ message because Mulesoft (SUT) transforms the message to another format.

I need to check what comes out of AMQ against a sample to make sure MuleSoft made the right transformation

[christophd]

@JensVanhulstSolita any news on this issue. did you find out what went wrong?
