[Koha] invalid data, cannot decode object

[Jonathan Druart]

It means you have missing biblio_metadata for some of your
bibliographic records.

Is it a new fresh install? Did you just upgrade to 19.05? How did you
import your records?

The following SQL query will return the biblionumber that do not have
a biblio_metadata entry:
SELECT COUNT(*) FROM biblio b LEFT JOIN biblio_metadata m ON
b.biblionumber=m.biblionumber WHERE m.biblionumber IS NULL;
