What is "not serializable" in this Groovy method?

I wrote the following function which is loaded to my pipeline:

def userTrigger() {
  [$class: 'UsernamePasswordMultiBinding', credentialsId: jenkins_creds, usernameVariable: 'J_USER', passwordVariable: 'J_PASS'],
  ]){
      cmd = "curl -s -u \${J_USER}:\${J_PASS} \${env.BUILD_URL}api/json | python -mjson.tool | grep userId | awk '{print \$2}' | tr -d '"|,' "
      def ut = sh(returnStdout: true, script: cmd)
      return ut
    }
}

The result should be the username of the one who triggered the build, before cleaning the output it looks like so:

"userId": "itaig",

Basically, this:

awk -F'"' '{print $4}'

would also give me the required output but i'm not sure how to escape chars in this statement too.

When I run the job, I get the following error:

java.io.NotSerializableException: org.codehaus.groovy.control.ErrorCollector
    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:860)
    at org.jboss.marshalling.river.RiverMarshaller.doWriteFields(RiverMarshaller.java:1032)
    at org.jboss.marshalling.river.RiverMarshaller.doWriteSerializableObject(RiverMarshaller.java:988)
    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:854)

I'm pretty much sure it has something to do with my tries of escaping the relevant characters but I have a feeling that I haven't done it right, I've tried escaping the (") in the end of the cmd line but to no avail.

Can you try and find my issue?

What is that right parenthesis and right bracket closing on line #3?

]){

It might be more of the double-quote vs single-quote then the escaping of characters - make sure they are are pairing up nicely.
