JBPMでクレーム・レスト・コールを実行するreturn PermissionDeniedException

Question

私はJBPM初心者で、最近jBPM Workbenchショーケース・ドッカー・イメージ、より具体的には採用プロセスを開始しました。すべてがコンソール上で正常に動作しますが、プロセスを制御するJBPMの残りのAPIを使用しようとしたときに、私はPermissionDeniedExceptionを取得しました。

[POST] /task/{taskId}/claimを使用してタスクを要求しているときにエラーが発生します。私は次の例外だ：、私は、ユーザーkatyを使用してタスクを要求しようとしている

私は理解していけないことをしますが、エラーは、ユーザーadminが権限を持っていない示しています！

Answer 1

例外を見ると、 'admin'ユーザーはHumanTaskが割り当てられているグループの一部ではありません。 TaskのPotentialOwnersのみがタスク操作を実行できます。タスク割り当てを確認し、それに応じて正しいユーザーを使用してタスク操作を実行してください。
