调用db.collection.doc显示Error: errCode: -401003？

console.log(rdata.data[0]._id)//打印输出_id

await db.collection(‘renyuan’).doc(rdata.data[0]._id).update({

icon: iurl

})

//输出错误：Uncaught (in promise) Error: errCode: -401003 api parameter type error | errMsg: parameter.data should be object instead of undefined;
