When downloading a directory on the web-app the item doesn't appear in the vault admin page (same session and all)
This happens when you set an email address for the completion notification.
----
(this was a report for a transient issue with the vault, which got fixed)
Also in the notification email, I got:
```
You have requested the following bundle from the Software Heritage
Vault:
Object Type: directory
Object ID: 00b4bcdff80e8b3c180e481c76709fc876958b8a
This bundle could not be cooked for the following reason:
Internal Server Error. This incident will be reported.
We apologize for the inconvenience.

```
1. check if swh-team or devs received the report (not from me on IRC)
2. check the error of the non cooked bundle
3. check if the hiccup on the web-app was a one time thing
