結局あたらしいプレイグランドを使ったみたい

過去のエラーメッセージからは、これでないかと思ったけど...

but it was due to a simple blank space in plural name ' Job Posting Sites'. took hours to figure it out. Seems it dose not handle the error , space at the beginning of a name.

:::note
I had change the my domain URL. Changing the my domain to the original value fixed the verify challenge system. I was able to complete the trail head.

So do not make any changes to my domain URL , use the existing provided by the playground, else the system cannot verify that all steps are complete.

ドメインURLを変更してしまいました。私のドメインを元の値に変更すると、検証チャレンジ システムが修正されました。登山口を完走することができました。

したがって、ドメイン URL には変更を加えず、プレイグラウンドによって提供される既存の URL を使用してください。そうしないと、システムはすべての手順が完了したことを確認できません。

I deactivated and activated my playground, and it didn't solve the problem.

I managed to solve it by disconnecting the playground and creating a new one. Thank you very much for helping.

プレイグラウンドを無効にしてから有効にしましたが、問題は解決されませんでした。

プレイグラウンドを切断し、新しいプレイグラウンドを作成することで問題を解決できました。ご協力いただき誠にありがとうございました。

You might have multiple Lighting pages with the same name. Go to Setup > Lightning App Builder. You need only 1 Lightning page. Delete all other pages with the same name. Or change the Label of the page.This error may occur due to some pre-existing configuration that you might have done for other challenges. I would suggest you try in a new trailhead playground.Reference:
