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

You can use the following function to convert LazyMap to a regular LinkedHashMap (it will keep the order of original data):

LinkedHashMap nonLazyMap (Map lazyMap) {
    LinkedHashMap res = new LinkedHashMap()
    lazyMap.each { key, value ->
        if (value instanceof Map) {
            res.put (key, nonLazyMap(value))
        } else if (value instanceof List) {
            res.put (key, value.stream().map { it instanceof Map ? nonLazyMap(it) : it }.collect(Collectors.toList()))
        } else {
            res.put (key, value)
        }
    }
    return res
}

... 

LazyMap lazyMap = new JsonSlurper().parseText (jsonText)
Map serializableMap = nonLazyMap(lazyMap);

or better use a readJSON step as noticed in earlier comments:

Map serializableMap = readJSON text: jsonText
