Minimal code to reproduce the bug.

import 'dart:convert';

import 'package:nip19/nip19.dart';

const nsec = "nsec1naqgy39qgwwkyfxn3fr07h52kmrue027n7x5tk7xmxutcur0m67sm7etev";

const relays = [
  "wss://purplepag.es",
  "wss://relay.primal.net",
  "wss://relay.damus.io",
  "wss://nos.lol",
  "wss://bwcervpt.mooo.com",
];

void main(List<String> arguments) async {
  final ndk = Ndk(
    NdkConfig(eventVerifier: Bip340EventVerifier(), cache: MemCacheManager()),
  );

  final keyPair = Nip19KeyPair.fromNsec(nsec);

  ndk.accounts.loginPrivateKey(
    privkey: keyPair.privateKey,
    pubkey: keyPair.publicKey,
  );

  final subscription = ndk.requests.subscription(
    filters: [
      Filter(kinds: [1059], pTags: [keyPair.publicKey], limit: 1),
    ],
  );

  subscription.stream.listen((giftWrap) async {
    try {
      final messageEvent = await ndk.giftWrap.fromGiftWrap(giftWrap: giftWrap);
      print(messageEvent.content);
    } catch (e) {
      // triggered
      print("Error 1");
    }

    try {
      final unwrapped = await ndk.giftWrap.unwrapEvent(wrappedEvent: giftWrap);
      final messageEventJson = await ndk.accounts
          .getLoggedAccount()!
          .signer
          .decryptNip44(
