What Operating System are you using (both controller, and any agents involved in the problem)?

Only using controller and the OS is Debian 12

Reproduction steps

I am running the following in a post build step

stage('PostBuild') {
            steps {
                script {
println "Calculating BUILD_DURATION"

Jenkins.instance?.items.each { job ->
  if (job.name == "Spotter_test") {

try {

  def build = job.getLastBuild()

    if ( build != null ) {
    //   def duration = build.getDuration()
    
      def currentTime = System.currentTimeMillis()
      def startBuild =  build.getStartTimeInMillis()
      def duration = currentTime - startBuild
    
      println "got Duration of " + duration

      def buildDuration = Util.getTimeSpanString(duration)
      
      println "Duration string: " + buildDuration

      def strMessage = String.format('''{
  "header": {
    "title": "Jenkins",
    "subtitle": "${JOB_NAME} ${BUILD_ID}",
  },
  "sections": [
    {
      "header": "${BUILD_STATUS}",
      "collapsible": false,
      "uncollapsibleWidgetsCount": 1,
      "widgets": [
        {
          "divider": {}
        },
        {
          "textParagraph": {
            "text": "Duration: %s"
          }
        },
        {
          "divider": {}
        },
        {
          "buttonList": {
            "buttons": [
              {
                "text": "OPEN BUILD",
                "onClick": {
                  "openLink": {
                    "url": "${BUILD_URL}"
                  }
                },
                "disabled": false
              },
            ]
          }
        }
      ]
    }
  ]
}''', buildDuration)
    

googlechatnotification message: strMessage, messageFormat: 'SIMPLE', threadKey: '${JOB_NAME} #${BUILD_ID}', url: '<chat space webhook URL>
                
    }

} catch (Exception e) {
  println "Failed with exception " + e
}
}

  }
}

                }
        }
'

When this is run with <messageFormat: "SIMPLE"> it sends the text to the specified chat space.
When the messageFormat is changed to "CARD" it throws this exception:

{"header":{"subtitle":"Spotter_test 172","title":"New Jenkins"},"sections":[{"header":"<font color=\"#5DBCD2\">SUCCESS<\/font>","uncollapsibleWidgetsCount":1,"widgets":[{"divider":{}},{"textParagraph":{"text":"Duration: %s"}},{"divider":{}},{"buttonList":{"buttons":[{"onClick":{"openLink":{"url":"http://192.168.15.140:8080/job/Spotter_test/172/"}},"disabled":false,"text":"OPEN BUILD"}]}}],"collapsible":false}]}
[Pipeline] echo
Failed with exception java.io.NotSerializableException: hudson.model.FreeStyleProject

Expected Results

To be able to display a card with the build results in Google Chat space.

Actual Results

Nothing shows up in the Google Chat space when messageFormat is set to "CARD"

Anything else?
