类型字符串属性列表中的React本机域筛选器项

以下是我的模式:

export class Employee {
}
Employee.schema = {
    name: 'Employee',
    primaryKey: 'employeeId'
    properties: {
        'employeeId':'string'
        'name': 'string',
        'age': 'string',
        'specialization': { type: 'string?[]' },
    }
};

我尝试了以下方法,但没有成功

let specialization = "java"
realm.objects('Employee').filtered("specialization CONTAINS $0", specialization)
