bug uni-file-picker无法显示图片

<uni-td align="center">
        <uni-file-picker v-if="item.avatar && item.avatar.fileType == 'image'" :modelValue="item.avatar" :file-mediatype="item.avatar && item.avatar.fileType" return-type="object" :imageStyles="imageStyles" readonly></uni-file-picker>
        <uni-link v-else :href="item.avatar && item.avatar.url" :text="item.avatar && item.avatar.url"></uni-link>
</uni-td>

把value改成modelValue就好了
