Handle nullable relationship in edit form

I have "Project" and "HumanResource" models. Each project has a "project manager" and "operational_manager", both belong to "HumanResource" model. i can create a project without mentionning the project and operational managers. In this case the "project_manager" and "operational_manager" will be null. When i don't set those fields i get the error in attachment. Otherwise, i pass normally. EditRecord Code :

Section::make()->schema([
                        Forms\Components\Select::make('project_manager')
                            ->relationship(name: 'projectManager', titleAttribute: 'full_name') 
                            ->searchable()
                            ->preload()
                            ->nullable(),
                        Forms\Components\Select::make('operational_manager')
                            ->relationship(name: 'operationalManager', titleAttribute: 'full_name')
                            ->searchable()
                            ->preload()
                            ->nullable()
]);

Section::make()->schema([
                        Forms\Components\Select::make('project_manager')
                            ->relationship(name: 'projectManager', titleAttribute: 'full_name') 
                            ->searchable()
                            ->preload()
                            ->nullable(),
                        Forms\Components\Select::make('operational_manager')
                            ->relationship(name: 'operationalManager', titleAttribute: 'full_name')
                            ->searchable()
                            ->preload()
                            ->nullable()
]);

relationship code in Project model :

public function projectManager()
    {
        return $this->hasOne(HumanResource::class, 'project_manager');
    }

    public function operationalManager()
    {
        return $this->hasOne(HumanResource::class, 'operational_manager');
    }

public function projectManager()
    {
        return $this->hasOne(HumanResource::class, 'project_manager');
    }

    public function operationalManager()
    {
        return $this->hasOne(HumanResource::class, 'operational_manager');
    }

Solution:

@toeknee i found the error in the relationship. instead of using "hasOne" i use "belongsTo" and it works...
