Product Ubuntu deb sync problem

Ubuntu 18.04 deb repo will not sync. When i try to sync it in products i am getting a warning (error code attached).
Any idea?

Expected outcome:
Foreman and Proxy versions:
Foreman 1.24.2
Katello 3.14.1
Pulp Versin 1.5.0

Foreman and Proxy plugin versions:

Distribution and version:

Other relevant data:

what is the error code ?

With previous foreman and katello versions (Foreman 1.23 Katello 3.13) the sync was working normally.
By sync he starts with green line and:
Copying units already in pulp (0/1)
After that it gets a Warning and stops the sync.
Any idea?
