无法将请求编组到 JSON：在授予 api 网关权限以使用无服务器模板调用 lambda 时，restapi_id 不能为空

如何解决无法将请求编组到 JSON：在授予 api 网关权限以使用无服务器模板调用 lambda 时，restapi_id 不能为空

我使用无服务器模板创建 lambda 和 api 网关，并使用 lambda 权限资源提供调用 lambda 函数的 api 网关权限。但出现以下错误。我在 lambda 权限资源中正确地给出了 restapi_id，但仍然低于错误。能否请您提供一些解决问题的建议

错误：列出 api 网关关系时发生错误：无法将请求编组到 JSON：无法将请求编组到 JSON：restapi_id 不能为空

请找到 serverless.template。
