Jenkins Pipeline NotSerializableException: groovy.json.internal.LazyMap

Question

Solved: Thanks to below answer from S.Richmond. I needed to unset all stored maps of the groovy.json.internal.LazyMap type whi

Answer 1

A slightly more generalized form of the answer from @mkobit which would allow decoding of arrays as well as maps would be:

import groovy.json.JsonSlurper

@NonCPS
def parseJsonText(String json) {
  def object = new JsonSlurper().parseText(json)
  if(object instanceof groovy.json.internal.LazyMap) {
      return new HashMap<>(object)
  }
  return object
}

NOTE: Be aware that this will only convert the top level LazyMap object to a HashMap. Any nested LazyMap objects will still be there and continue to cause issues with Jenkins.
