Backup page blank when clicking "Back" button in CloudStack 4.21

[jeanvetorello]

I have fully configured the Backup Framework in CloudStack 4.21, including a working Backup Service Offering using a NAS provider.
The backups are created successfully — they appear correctly when using the API or CloudMonkey command list backups, and the job status is Completed.

Steps to Reproduce

Log in to the CloudStack Primate UI version 4.21.0
Go to Instances → select a VM → Backups tab.
Click on a specific backup to open its details.
Click Back (top-left corner).
Observe: the entire page turns white and no content reloads.

@jeanvetorello could this be browser caching issue?
Could you please try the steps again in a private window?

Do the backups show up in Storage->Backups section?

I did the same test in an incognito window, and the same error occurred.

Hi @jeanvetorello could you please share the full console log and network tab response output as shown above?
