Hi,

this is caused by an entry in the source table not having a matching
entry in the organisationunit table, probably because someone deleted
an orgunit without deleting the corresponding source from the
database.

Do a sql query:

delete from organisationunit where organisationunitid not in ( select
sourceid from source )
