为什么调用uni-data-picker的clear方法会报以下错无法清空选中的值
[
{
"text": "mvlkfdljg",
"value": "1-0",
"children": [
{
"text": "jpjrewqr",
"value": "1-1",
"children": [
{
"text": "216446894",
"value": "1-1-1"
}
]
},
{
"text": "vcsafdas",
"value": "1-2",
"children": [
{
"text": "265645168",
"value": "1-2-1"
}
]
}
]
},
{
"text": "eqwsadqwe",
"value": "2-0",
"children": [
{
"text": "fwefweqf",
"value": "2-1",
"children": [
{
"text": "2164649845",
"value": "2-1-1"
},
{
"text": "123346123",
"value": "2-1-2"
}
]
}
]
}
]
