Invenio 1: BibRank exception

I was getting several exceptions in Bibrank:

** Stack frame details

This was solved by updating /opt/invenio/etc/bibrank/citation.cfg with citation_loss_limit = 50 and I also included some more options:

[...]
reference_via_doi= 999C5a
reference_via_record_id= 990C50
reference_via_isbn= 999C5i
[...]
citation_loss_limit = 50
collections =

Then it was solved 🙂
