uniapp开发中，Unhandled error during execution of watcher callback

<uni-forms ref="formref" :model="form" label-width="80px" :rules="rules">
        <uni-forms-item label="机构全称" prop="fullName" required>
          <uni-easyinput v-model="form.fullName" placeholder="请输入机构全称" />
        </uni-forms-item>
		<uni-forms-item label="服务对象" name="serviceObject">
		  <uni-data-checkbox v-model="form.serviceObject" :localdata="serviceObjectOptions" multiple @change="change"/>
		</uni-forms-item>

uni-data-checkbox的v-model绑定变量form.serviceObject，在初始化值时，若serviceObject初始值为null，那么编译运行时就会出现和localdata值有关的Unhandled error during execution of watcher callback错误，经过多次排查，将serviceObject初始化为一个空数组，问题得到解决。
