Error with changeSet in jenkins pipeline (Error:java.io.NotSerializableException: hudson.plugins.git.GitChangeSetList)

[Yolanda Lopez]

I have this error:

java.io.NotSerializableException: hudson.plugins.git.GitChangeSetList

when ChangeSet!=null but the strange is that the error ocurred when updating this plugin: Pipeline Shared Groovy Libraries, before this work good, i use jenkins v 2.21 and pipeline 2.4 and my code is the next:

def changeLogSets = currentBuild.rawBuild.changeSets
for (int i = 0; i < changeLogSets.size(); i++) {
   def entries = changeLogSets[i].items
   for (int j = 0; j < entries.length; j++) {
        def entry = entries[j]
        echo "${entry.commitId} by ${entry.author} on ${new Date(entry.timestamp)}: ${entry.msg}"
        def files = new ArrayList(entry.affectedFiles)
        for (int k = 0; k < files.size(); k++) {
            def file = files[k]
            echo "  ${file.editType.name} ${file.path}"
        }
    }
}
changeLogSets= null
