Error Handling

The error handling in the auxiliary drop steps (inside the for‐loop) should be checked to ensure that only NamespaceNotFound errors are suppressed. It is important to validate that no unexpected errors are swallowed.

for (const collectionName of [escCollection, ecocCollection]) {
    // Drop auxilliary collections, ignoring potential NamespaceNotFound errors.
    const dropOp = new DropCollectionOperation(db, collectionName);
    try {
        await dropOp.executeWithoutEncryptedFieldsCheck(server, session, timeoutContext);
    }
    catch (err) {
        if (!(err instanceof error_1.MongoServerError) ||
            err.code !== error_1.MONGODB_ERROR_CODES.NamespaceNotFound) {
            throw err;
        }
    }
}
Recursion Safety

The recursive instantiation of DropCollectionOperation for auxiliary collections could lead to unintended drop operations if the encryptedFields configuration is misconfigured. A review of both the recursive call and its termination criteria is recommended.

const escCollection = encryptedFields.escCollection || `enxcol_.${name}.esc`;
const ecocCollection = encryptedFields.ecocCollection || `enxcol_.${name}.ecoc`;
for (const collectionName of [escCollection, ecocCollection]) {
    // Drop auxilliary collections, ignoring potential NamespaceNotFound errors.
    const dropOp = new DropCollectionOperation(db, collectionName);
    try {
        await dropOp.executeWithoutEncryptedFieldsCheck(server, session, timeoutContext);
    }
    catch (err) {
        if (!(err instanceof error_1.MongoServerError) ||
            err.code !== error_1.MONGODB_ERROR_CODES.NamespaceNotFound) {
            throw err;
        }
    }
}
