jsonSchema2pojo jackson deserialisation issue

问题

I am trying use jsonSchema2pojo POJO generating library and i am successful in doing so as well. But issue i am facing is deserialisation Exception when i try to generate map by typeReferencing generated rootClass i.e EsRootDoc(in below code).

Here , is the code that i am testing:

JCodeModel codeModel = new JCodeModel();
String classLocation = System.getProperty("user.dir")+ "/src/main/java";
GenerationConfig config = new DefaultGenerationConfig() {
                @Override
                public boolean isGenerateBuilders() { // set config option by overriding method
                    return true;
                }

                @Override
                public SourceType getSourceType() {
                    return SourceType.JSON;
                }
final RuleFactory ruleFactory = new RuleFactory(config,
            new Jackson2Annotator(config), new SchemaStore());

            final SchemaMapper mapperSchema = new SchemaMapper(ruleFactory,new SchemaGenerator());

    mapperSchema.generate(codeModel, "EsRootDoc",           "com.tech.EnrichmentService.EnrichmentController.tempJsonToClass", json);

codeModel.build(new File(classLocation));

ObjectMapper mapper = new ObjectMapper();
try{

     p = mapper.readValue(json,new TypeReference<com.tech.EnrichmentService.EnrichmentController.tempJsonToClass.EsRootDoc>() {});

    }
    catch(Exception e){
    e.printStackTrace();
    }

Exception :

  com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_ARRAY token
 at [Source: java.io.StringReader@72b070e8; line: 1, column: 15974] (through reference chain: com.tech.EnrichmentService.EnrichmentController.tempJsonToClass.EsRootDoc["svo"]->java.util.ArrayList[1]->com.tech.EnrichmentService.EnrichmentController.tempJsonToClass.Svo["svoMetadata"]->com.tech.EnrichmentService.EnrichmentController.tempJsonToClass.SvoMetadata["event"])

Now, If i am generating classes here and then typeReferencing same generated rootClass , how do i get to dissimilar json to Pojo issue ??

Editted(added json):
