无法在 Orientjs 中创建 EDGE

Question

我正在使用 OrientJS，我正在尝试在两个节点之间创建一条边。直到几天前，使用以下脚本一切正常：

module.exports.insertRelatedToAssociation = (nodeFrom, nodeTo) => {
    db.create('EDGE', 'RelatedTo')
        .from(nodeFrom).to(nodeTo)
        .one()
        .then(function (result) {
             return (result !== undefined)
         })     
}

但是现在，我每次运行脚本时都会突然收到此错误消息：

com.orientechnologies.orient.core.sql.OCommandSQLParsingException: Error parsing query:
CREATE EDGE RelatedTo FROM #29:5
     ^
Encountered " <CREATE> "CREATE "" at line 1, column 1.

也许，OrientDB 更改了它的解析器，但我在 GitHub Wiki (https://github.com/orientechnologies/orientdb/wiki/OrientDB-2.2-Release-Notes#2226---august-16-2017) 上没有找到任何相关信息。

注意：我正在运行安装 orientdb-community-importers-2.2.24。 2.2.26版本也一样。

我发现了错误。只是参数 nodeFrom 是 undefined。因此将 undefined 传递给 db.create('EDGE','RelatedTo).from(undefined).to(nodeTo) 会产生该错误！
