# However, in the past, some users with roles may have been deleted – without the corresponding roles being

Error while re-assigning Service \##{service.id} to another Administrateur.
|
||
|
||
We tried to re-assign the Service \##{service.id} to another Administrateur,
|
||
but none of the Procedures (#{service.procedures.pluck(:id)}) attached to this Service had other Administrateurs
|
||
to assign the service to.
|
||
|
||
Please fix the Service \##{service.id} manually (by assigning it to any valid administrator, for instance the
|
||
first one in your database), then run this task again.
