Can't migrate account from misskey

[nakkaa]

(Maybe it is a bug in Misskey. If so, I apologize.)

I can't migrate account from misskey to hollo.
The following error occurs in Misskey.

Destination account doesn't have proper 'Known As' alias, or has already moved.

Adding multiple aliases on the Hollo side allows for successful migration.

Environment

• Misskey v2025.3.1 and v2025.4.1.alpha.2
• Hollo v0.6.0-dev.14

Could you let me know what's your source account and destination account?

[nakkaa]

source https://maniakey.com/@anahibi
destination https://ml.7ka.org/@anahibi

[dahlia]

Your destination account already has a “known as” alias to your source account:

{
  "@context": [
    // ...
  ],
  "id": "https://ml.7ka.org/@anahibi",
  "type": "Person",
  // ...
  "alsoKnownAs": [
    "https://maniakey.com/users/9m94d6c51e",
    "https://misskey.7ka.org/users/a6unuoo4vt",
    "https://ml.7ka.org/@john"
  ],
  // ...
}

I think the Misskey instance that your source account belongs to cached the outdated data of your destination account… You could invalidate the cache by clicking Update remote user information (リモートユーザー情報の更新) in the menu from a remote profile:

aliasを1つしか指定せずに、移行に失敗したケースを用意しました。

source: https://misskey.7ka.org/@test0422
destination: https://ml.7ka.org/@test0422

1. Misskeyでアカウントを作成します。
2. Holloでアカウントを作成します。
3. Holloで1のアカウントのaliasを追加します。
4. MisskeyでHolloのアカウントを開き、「リモートユーザー情報の更新」を実行します。
5. MisskeyからHolloのアカウントへ引っ越しを実行します。

この際、 Destination account doesn't have proper 'Known As' alias, or has already moved. が発生します。

Misskey側のデータベースで次のSQLを実行すると、どの様な結果が出ますか？

SELECT "user"."alsoKnownAs", "user"."movedToUri"
FROM "user"
WHERE "user"."uri" = 'https://ml.7ka.org/@test0422';

[nakkaa]

結果は以下のとおりでした。

=# SELECT "user"."alsoKnownAs", "user"."movedToUri"
FROM "user"
WHERE "user"."uri" = 'https://ml.7ka.org/@test0422';
               alsoKnownAs                | movedToUri

不思議ですね。私の考えでは、Misskey側のバグである可能性が高いです。Misskey側のイベントトラッカーにもイシューを作成してみてもらえますか？
