Javascript 如何将null数据类型和number数据类型集成到我的模式中？

我编写了一个模式，发现EventId响应返回为数字或null，但乍一看，我认为响应只是数字，但我错了，它们都是错误的，如下所示： AssertionError:无效类型：null（预期数字）：预期false等于true

如何在模式中容纳这两种数据类型，即number或null

架构如下：

tests['Status code is 200'] = pm.response.to.have.status(200);

 pm.test('Schema is valid', function() {
 var response = pm.response.json();
   var result = tv4.validateResult(response, schema, false, true);
 pm.expect(result.valid).to.equal(true, result.valid ? null : result.error.message);
});

我现在做了一些研究，似乎你可以有多种数据类型，只需编辑你的类型，例如

"type": ["number", "null"]

但我似乎仍然得到相同的错误断言error:Invalid type:null（预期对象）：expected false等于true..因此我想我需要代码来告诉我的模式number或null是可以接受的，但是如何做呢？

AssertionError: Invalid type: null (expected object): expected false to equal true

声明您正在返回

null

，其中您的架构验证需要

对象

。如果空响应有效，则需要对此进行说明

"type": ["object","null"]
