[英]Azure Custom resource provider - custom error message to ARM template
If my custom resource provider wants to return a custom failure message to ARM, what should be my response body?如果我的自定义资源提供程序想要向 ARM 返回自定义失败消息,我的响应正文应该是什么? I have a custom resource provider backed by a JavaScript Azure function I tried the following
我有一个由 JavaScript Azure 函数支持的自定义资源提供程序,我尝试了以下操作
body = {
error: {
code: "Failed",
message: "A custom error message'."
}
};
httpStatus = 200;
context.res = {
status: httpStatus,
headers: {
'Content-Type': 'application/json'
},
body: body
};
The ARM template deployment fails with error - ARM 模板部署失败并出现错误 -
{
"error": {
"code": "ResourceDeploymentFailure",
"message": "The response for resource had empty or invalid content."
}
I also tried我也试过
body = {
properties: {
provisioningState: "Failed",
error: {
code: "Failed",
message: "A custom error message'."
}
}
};
httpStatus = 200;
context.res = {
status: httpStatus,
headers: {
'Content-Type': 'application/json'
},
body: body
};
The ARM template deployment fails with error ARM 模板部署失败并出现错误
"The resource operation completed with terminal provisioning state 'Failed"
I want the ARM template deployment to fail with a custom error message I return form the Azure function - "A custom error message'."我希望 ARM 模板部署失败并显示我从 Azure 函数返回的自定义错误消息 - “自定义错误消息”。

Here is my ARM template这是我的 ARM 模板
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"resourcePrefix": {
"type": "string",
"defaultValue": "prfx-",
"maxLength": 6,
"metadata": {
"description": "The prefix of HLF resource."
}
},
"randomGuid": {
"defaultValue": "[newGuid()]",
"type": "string",
"metadata": {
"description": "New random GUID"
}
}
},
"variables": {
"funcName": "[concat(parameters('resourcePrefix'), substring(parameters('randomGuid'), 0, 5))]",
"myResourceProvider": "my-custom-provider",
"location": "[resourceGroup().location]"
},
"resources": [
{
"apiVersion": "2018-09-01-preview",
"type": "Microsoft.CustomProviders/resourceProviders",
"name": "[variables('myResourceProvider')]",
"location": "[variables('location')]",
"properties": {
"resourceTypes": [
{
"name": "deploy",
"routingType": "Proxy",

}
]
}
},
{
"apiVersion": "2018-09-01-preview",
"type": "Microsoft.CustomProviders/resourceProviders/deploy",
"name": "[concat(variables('myResourceProvider'), '/', variables('funcName'))]",
"location": "[variables('location')]",
"dependsOn": [
"[concat('Microsoft.CustomProviders/resourceProviders/',variables('myResourceProvider'))]"
]
}
],
"outputs": {
}
}
Proxying the error message as is, is not currently supported for Custom Providers.自定义提供程序当前不支持按原样代理错误消息。 The custom error message would be nested as details under a standard message.
自定义错误消息将作为详细信息嵌套在标准消息下。
However, it looks like there is a bug that is stopping the propagation of the error through the ARM template.但是,看起来有一个错误正在阻止错误通过 ARM 模板传播。 This should be fixed soon!
这应该很快修复!
@jjbfour is right. @jjbfour 是对的。 The custom message is nested under "Downstream" label in the propagated message.
自定义消息嵌套在传播的消息中的“下游”标签下。 But that is fine for me.
但这对我来说很好。 The following works
以下作品
body = {
error: {
code: "Failed",
message: "A custom error message'."
}
};
httpStatus = 400;
context.res = {
status: httpStatus,
headers: {
'Content-Type': 'application/json'
},
body: body
};
The mistake I was making earlier was not setting the HTTP status correctly.我之前犯的错误是没有正确设置 HTTP 状态。
