_deleteTKeyStoreItem cause error

[minhnd410]

Step to reproduce

1. assumed login and reconstruct key successfully
2. create item: _setTKeyStoreItem(module: "A", {id: 1, data: ...})
3. create other item: _setTKeyStoreItem(module: "A", {id: 2, data: ...})
4. try delete one of them: _deleteTKeyStoreItem(module: "A", id: 2})
5. execute getTKeyStore("A") cause error

Error

The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined

Investigate

The following method cause error

  async _deleteTKeyStoreItem(moduleName: string, id: string): Promise<void> {
    if (!this.metadata) {
      throw CoreError.metadataUndefined();
    }
    const rawTkeyStoreItems = (this.metadata.getTkeyStoreDomain(moduleName) as EncryptedMessage[]) || [];
    const decryptedItems = await Promise.all(
      rawTkeyStoreItems.map(async (x) => {
        const decryptedItem = await this.decrypt(x);
        return JSON.parse(decryptedItem.toString()) as TkeyStoreItemType;
      })
    );
    const finalItems = decryptedItems.filter((x) => x.id !== id);
    this.metadata.setTkeyStoreDomain(moduleName, finalItems);
    await this._syncShareMetadata();
  }

Suggested Correction

  async _deleteTKeyStoreItem(moduleName: string, id: string): Promise<void> {
            if (!this.tKey.metadata) {
                throw CoreError.metadataUndefined();
            }
            const rawTkeyStoreItems = (this.tKey.metadata.getTkeyStoreDomain(moduleName) as EncryptedMessage[]) || [];
            const decryptedItems = await Promise.all(
            rawTkeyStoreItems.map(async (x) => {
                  const decryptedItem = await this.tKey.decrypt(x);
                  return JSON.parse(decryptedItem.toString()) as TkeyStoreItemType;
                })
            );
            const finalItems = decryptedItems.filter((x) => x.id !== id);

            const finalRawTkeyStoreItems: EncryptedMessage[] = []
            for (let i = 0; i < finalItems.length; i++) {
                const encryptedData = await this.tKey.encrypt(Buffer.from(stringify(finalItems[i])));
                finalRawTkeyStoreItems.push(encryptedData)
            }
    
            this.tKey.metadata.setTkeyStoreDomain(moduleName, finalRawTkeyStoreItems);
            await this.tKey._syncShareMetadata();
  }
