【问题描述】：

我正在从 js 迁移到 ts 以及从 mongoose 5.8 到 6.1 以下代码之前运行良好

let getActionsTakenByApp = (store_url: string) => 
    return AppAction.aggregate([
        
            $match:  store_url 
        ,
        
            $group: 
                _id: 
                    'action_type': '$action_type'
                ,
                count: 
                    $sum: 1
                
            
        
    ]);

但是现在打字稿现在显示这个错误。

Type ' _id:  action_type: string; ; count:  $sum: number; ; ' is not assignable to type ' [key: string]:  $count?: any; $accumulator?: any; $addToSet?: any; $avg?: any; $first?: any; $last?: any; $max?: any; $mergeObjects?: any; $min?: any; $push?: any; $stdDevPop?: any; $stdDevSamp?: any; $sum?: any; ; _id: any; '.   Property '_id' is incompatible with index signature.
    Type ' action_type: string; ' is not assignable to type ' $count?: any; $accumulator?: any; $addToSet?: any; $avg?: any; $first?: any; $last?: any; $max?: any; $mergeObjects?: any; $min?: any; $push?: any; $stdDevPop?: any; $stdDevSamp?: any; $sum?: any; '.
      Object literal may only specify known properties, and ''action_type'' does not exist in type ' $count?: any; $accumulator?: any; $addToSet?: any; $avg?: any; $first?: any; $last?: any; $max?: any; $mergeObjects?: any; $min?: any; $push?: any; $stdDevPop?: any; $stdDevSamp?: any; $sum?: any; '.ts(2322)

我还是打字稿的新手，并试图找出问题所在。任何帮助，将不胜感激！谢谢！！
