tryCatch Юнит тестирование с Jest

Question

Я пытаюсь протестировать код tryCatch с шуткой, но продолжаю получать сообщение об ошибке, в настоящее время я попробовал

student. js

async checkStudentExist(studentName) {
        try {
            const studentExist = await this.StudentRepository.getOne({name: studentName})
            if (studentExist) {
                throw new Error(`Student already exist with the name: ${studentName}`)
            }
            return studentExist
        } catch (error) {
            throw error   
        }
    }

student.test . js

it('should throw an error if the input name already exist in database', async () => {
    mockGetOne.mockReturnValue(Promise.resolve(expectedOrganization))
    await studentService.checkStudentExist('john doe')
    expect(mockGetOne).toHaveBeenCalledWith({name: 'sample org'})
    expect(studentService.checkStudentExist('john doe')).resolves.toThrowError(new Error(`Organization already exist with the name: john doe`))
})

и это ошибка, которую я получаю
