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

EDIT: As pointed out by @Sunvic in the comments, the below solution does not work as-is for JSON Arrays.

I dealt with this by using JsonSlurper and then creating a new HashMap from the lazy results. HashMap is Serializable.

I believe that this required whitelisting of both the new HashMap(Map) and the JsonSlurper.

@NonCPS
def parseJsonText(String jsonText) {
  final slurper = new JsonSlurper()
  return new HashMap<>(slurper.parseText(jsonText))
}

Overall, I would recommend just using the Pipeline Utility Steps plugin, as it has a readJSON step that can support either files in the workspace or text.
