json - 部署模板解析失败 : 'Required property ' type' not found in JSON. 路径 ''，行，位置。'。 (代码:无效模板)

Question

我使用 Azure 门户在 Azure 中部署了 SQL 托管实例，在实际部署之前，它可以选择保存模板以便将来部署自动化，我就是这么做的。

然后我删除了托管实例，现在我需要使用生成的模板重新部署它。

当我在 Azure 门户中转到“部署自定义模板”时，从库中选择一个模板，然后 Azure 门户抛出验证错误:

Deployment template parse failed: 'Required property 'type' not found in JSON. Path '', line 256, position 27.'. (Code: InvalidTemplate)

模板由两个文件组成，parameters.json 和 template.json

看看parameters.json，它是一个短文件，甚至没有第256行，而template.json则有第256行(还有更多):

255       "federatedClientId": {
256         "type": "string",
257          "defaultValue": ""
258       },

这有点奇怪 - 它有“type”属性。
谷歌搜索和使用 Bing AI 并没有给我提供有意义的解决方案。我该如何修复它并使其正常工作？

Answer 1

Deployment template parse failed: 'Required property 'type' not found in JSON. Path '', line, position.'. (Code: InvalidTemplate): -

错误消息显示模板无效。确保模板格式正确 (Json)，没有过多的空格 &
''。 Arm 模板还可以使用 template validator 进行验证.

如果模板看起来仍然不错，请尝试使用所有必需的属性重新部署它。

正如您所做的那样，我创建了一个 SQL 托管实例并删除了部署。当我使用以下 parameters.json 文件使用自定义模板时，它按预期工作。
