encryptData(pubKey, message)

【参考方案1】：

我遇到了同样的问题，它发生是因为在您加载变量 pubkeys 的部分：

  pubkeys = pubkeys.map(async (key) => 
      return (await openpgp.key.readArmored(key)).keys[0]
    )

需要改成这样的promise：

let publicKeysPromises = pubkeys.map(async (key) => 
      return (await openpgp.key.readArmored(key)).keys[0]
    );

由于它是异步操作，并且在完全解决之前在“options”变量中使用“pubkeys”会导致问题。发生这种情况是因为当使用 'options' openpgp.encrypt(options) 调用函数 'encrypt' 时，openPGP 对名为 getPrimaryUser 的函数进行了内部调用。当使用 readArmored 读取公钥时，它会创建一个 Key 对象，该对象又将“getPrimaryUser”作为异步函数附加到它上面。因此，在调用“加密”函数之前，需要先解决上述承诺。

因此，接下来，您需要将选项更改为以下代码：

 const options = 
    message: openpgp.message.fromText(message),
    // resolve all promises returned before
    publicKeys: await Promise.all(publicKeysPromises),       // for encryption
    privateKeys: [privKeyObj]                         // for signing (optional)
    

我希望这能回答这个问题。
