Firebase函数成功完成1-2次，然后引发错误：无法修改已提交的WriteBatch

如何解决Firebase函数成功完成1-2次，然后引发错误：无法修改已提交的WriteBatch

我使用批处理写入firestore，而我的firebase-functions代码总是在第一次尝试时成功执行。

i  functions: Beginning execution of "myFunction"
i  functions: Finished "myFunction" in ~1s
i  functions: Beginning execution of "myFunction"
   API fetch ...
   Amount of records to process: 3600
   filled batch (amount of writes: 490)
   filled batch (amount of writes: 490)
   ...
   All batches commited to Firebase
   imported batch
   imported batch
   ...
i  functions: Finished "myFunction" in ~33s

该错误总是在函数的第二次或第三次执行时发生，并显示以下错误消息：

Unhandled error Error: Cannot modify a WriteBatch that has been committed.

我使用批处理的方法包括两个步骤。

1. 我创建了一个具有批次的数组，并向每个批次传递了490次写入。
2. 我执行await Promise.all()内的每个提交操作

我想我的错误是在步骤2中。我尝试了Promise链和异步等待：

异步/等待：

try {
    await Promise.all(batches.map(batch => batch.commit()))
    console.log('All batches commited to Firebase')
} catch (error) {
    console.log(error)
}

承诺链：

await Promise.all(batches.map(batch => {
    return batch.commit().then(function () {
        console.log("imported batch")
    });
}))
    .then(console.log('All batches commited to Firebase'))
    .catch(err => console.log(err))

batchs数组本身就是这样创建的，我在循环中多次调用以下函数：

function useBatches(collectionRef,action,type,docId,data) {
    
    const docRef = collectionRef.doc(docId);

    switch(action) {
        case 'delete':
            batches[batchIndex].delete(docRef);
            break;
        case 'update':
            batches[batchIndex].update(docRef,data);
            break;
        case 'set':
            batches[batchIndex].set(docRef,data);
            break;
    }
    batchSizeCounter++;
    totalWritesTodo--

    // create batches
    if (batchSizeCounter === BATCH_SIZE) {
        console.log(`filled batch (amount of writes: ${batchSizeCounter})`)
        batches.push(db.batch());
        batchIndex++;
        batchSizeCounter = 0;
    }

    // inform about last batch was filled
    if (totalWritesTodo === 0) {
        console.log(`filled batch (amount of writes: ${batchSizeCounter})`)
        return;
    }
}

非常感谢您的帮助！
