Current Behavior

For an unexplained reason some subdomain does not launch any scan.
When you click Initiate scan, task is sent to celery but the following log is present:

rengine-celery-1       | initiate_subscan                   | WARNING | https://img-dev.xxx.com [200] `0B` `Apache` `159.114883ms`

rengine-celery-1       | ================================http_crawl

Important line is this on

rengine-celery-1       | dir_file_fuzz                      | WARNING | []

No URL is present, so scan cannot start.

After further investigation, problem comes from the database.
In the endpoint table, there is default endpoints, and for every subdomain without a default entry on base subdomain (https://www.xxx.com) scan will not start.

Here my sub that not scan

The default entry is set while doing a target scan after that it is never set elsewhere.
So if there is a problem while setting this value, subdomains are listed, but you can't launch any scan on it.

Workaround

If True is set to is_default value in the DB scan will work properly
So got to /admin and edit the desired value in the endpoint table.
Then relaunch the scan

Expected Behavior

Scan should start for a subdomain present in the table

Steps To Reproduce

Random, some domain works, others not.
Need investigation
