'Aws dynamo db mapper is not converting data

log audit method is trying to covert complex json string into map to store data in the form of json into dynamodb table but ending with error java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.amazonaws.services.dynamodbv2.model.AttributeValue

class AuditService{

            @Autowired
            AuditRepository auditRepository;
            ObjectMapper mapper = new ObjectMapper();
            public void logAudit(HttpServletRequest httpServletRequest, HttpServletResponse servletResponse) {
                
            Audit audit= new Audit();
            // coverting complex json string to map with help of mapper 
            audit.setEncryptedRequest(mapper.readValue(complex_multiLevel_json_String, new TypeReference<Map>() {})
            
            audit.save();
            }
          }

                    this.encryptedRequest = encryptedRequest;
                }
                }








complex json string which need to store into dynamo db table in the form of map:

note : we don't want to create a model class with below json attribute as field and then storing those model class to dynamo db
