I want to create a task and assign it to a new project

for project in data: 

    project_tasks = project['tasks'] 

    for task in project_tasks: 

        project_id = get_or_create_project(project['name']) 

        employee_id = get_or_create_employee(task['assigned_to']) 

        new_task = request.env['project.task'].sudo().with_context(check_move_validity=False).create({ 

        'name': task['name'], 

        'description': task['desc'],        
        }) 

        new_task.update({'user_id': [( 4, employee_id, 0  )]}) 

        new_task.update({'project_id': [( 4, project_id, 0 )]})


def get_or_create_project(project_name):    
    p_exists = request.env['project.project'].search([('display_name', '=', project_name)])    
    if p_exists:        
        project_id = p_exists.id    
    else:        
        new_project = request.env['project.project'].sudo().with_context(check_move_validity=False).create({            
        'name': project_name,        
        })        
        project_id = new_project.id    
return project_id

def get_or_create_employee(employee_name):    
    e_exists = request.env['hr.employee'].search([('name', '=', employee_name)])    
    if e_exists:        
        employee_id = e_exists.id    
    else:        
        new_employee = request.env['hr.employee'].sudo().with_context(check_move_validity=False).create({            
        'name': employee_name,        
        })        
        employee_id = new_employee.id    
    return employee_id

Thank you
