### The required feature described as a wish
Thank you, @Pearl1594, for helping confirm that the root cause of the
failure was:
The attached ISO was no longer available after the storage was
decommissioned.
The system didn’t provide proper error handling for this case (`"templateVO"
was null`), resulting in a generic and unclear message.

```
Would it be possible to improve the error message for this scenario? A more
descriptive message would help regular users understand the issue without
needing admin assistance.
Additionally, administrators could benefit from seeing more detailed
information when the failure isn’t directly related to a missing ISO.
Thank you and regards,
