我的java后端代码如下：
public void completeTask(String taskId, String comment, Integer userId, String outcome) {
Task task=taskService.createTaskQuery().taskId(taskId).singleResult();
Authentication.setAuthenticatedUserId(userId+"");
taskService.addComment(taskId, task.getProcessInstanceId(), comment);
if(outcome==null) {
taskService.complete(taskId);
}else {
Map<String,Object> map=new HashMap<String,Object>();
map.put("outcome",outcome);
taskService.complete(taskId,map);
}
}
在执行到taskService.complete(taskId,map)报错，报的框架里面的问题，我想的应该不会，框架的兼容性也测试过了没问题，找不到是哪里的原因，报错如下，请大神帮助

Could not set property 'byteArrayRef' of 'VariableInstanceEntity[id=9703, name=userId, type=integer]' with value 'ByteArrayRef[id=null, name=null, entity=null]' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'byteArrayRef' in 'class org.activiti.engine.impl.persistence.entity.VariableInstanceEntity'] with root cause
报错大概意思是说，VariableInstanceEntity对象中的byteArrayRef属性没有set方法。
检查一下你这个字段byteArrayRef 在数据库 Mapper和实体类中的写法和类型是否一致
你把这句删掉试试, 这个应该是提交流程的时候才会用到
Authentication.setAuthenticatedUserId(userId+"");另外再检查一下 你是否有下个节点需要用到的数据,
就比如你的map参数里 缺了下个节点要用到的数据,然后导致你现在的审批出错
