原因

Database contains a null value for the watcher's count.

ソリューション

  • Verify if there are problematic issues via the database by running this SQL query:

    select id,pkey,watches from jiraissue where watches is null;
  • Once confirmed, update this list to populate the watches column to have the value of 0 (zero).

    データベースの変更を行う場合は 必ず事前にバックアップを取得してください。可能な場合はテスト サーバーで変更を試すことをおすすめします。
