• Details of failed Job UI page
  

• Output of failed Job UI page
  

• Downloaded output of failed Job UI page (empty)

This makes debugging jobs very difficult.

ENVIRONMENT

• AWX version: 16.0.0
• AWX install method: kubernetes

EXPECTED RESULTS

I expect to see job_explanation such as

Job cannot start because Credential Shared Ansible Vault Password does not provide one or more required fields (vault_password). Task failed pre-start check.
To be visible somewhere in the UI

Thanks! I wasn't sure if the issue was reporting the same UI error, but now I see that it is.
