KVManager. getKVStore总是失败?

const options: distributedKVStore.Options = {
  createIfMissing: true,
  encrypt: true,
  backup: true,
  autoSync: true,
  kvStoreType: distributedKVStore.KVStoreType.SINGLE_VERSION,
  securityLevel: distributedKVStore.SecurityLevel.S2
};
this.kvStore = await this.kvManager.getKVStore(KVStorage.storeId, options);
