使用Bicep创建Logic App服务总线API连接部署报错排查

我正尝试使用Bicep创建面向Service Bus的Logic App API连接，初始编写的Bicep代码如下：

resource ServicebusApiCon 'Microsoft.Web/connections@2016-06-01' = {
  name: 'servicebus123'
  location: Location
  kind: 'V2'
  properties: {
    displayName: 'servicebus'
    api: {
      name: 'servicebus'
      id: '/subscriptions/${subscription().subscriptionId}/providers/Microsoft.Web/locations/${Location}/managedApis/servicebus'
      type: 'Microsoft.Web/locations/managedApis'
      parameterValueSet: {
        name: 'managedIdentityAuth'
        values: {
          namespaceEndpoint: {
            value: 'https://servicebus.servicebus.windows.net:443/'
          }
        }
      }

    }
  }
}

编写时参考了存储账户、Key Vault的托管身份认证参数配置，对应片段如下：

for storage account:
 parameterValueSet: {
    name: 'managedIdentityAuth'
    values: {
      accountName: 'storageaccountname'
       
    }
  }
 for keyvault:
    parameterValueSet: {
      name: 'managedIdentityAuth'
      values: {
        vaultName: 'keyvaultname'
       
    }     
  
}

执行部署操作时出现如下报错，需要确认现有代码是否存在配置缺失或错误，以及对应的修复方法：

{
  "status":"Failed",
  "error":{
    "code":"DeploymentFailed",
    "message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.",
    "details":[
      {
        "code":"BadRequest",
        "message":{
          "error": {
            "code": "InvalidRequestContent",
            "message": "The request content is not valid and could not be deserialized: 'Could not find member 'parameterValueSet' on object of type 'ManagedApiReference'. Path 'parameterValueSet', line 1, position 258.'"
          }
        }
      }
    ]
  }
}

配置层级写错：parameterValueSet不是properties.api（即类型为ManagedApiReference的api对象）的合法属性，该配置节点放置位置错误，导致Azure资源管理器无法解析请求内容，抛出反序列化错误。

将parameterValueSet节点从properties.api路径下移动到properties根层级，与displayName、api节点保持平级即可。
修复后的Service Bus API连接Bicep代码如下：

resource ServicebusApiCon 'Microsoft.Web/connections@2016-06-01' = {
  name: 'servicebus123'
  location: Location
  kind: 'V2'
  properties: {
    displayName: 'servicebus'
    // 托管身份认证参数配置移至properties根层级
    parameterValueSet: {
      name: 'managedIdentityAuth'
      values: {
        namespaceEndpoint: {
          value: 'https://servicebus.servicebus.windows.net:443/'
        }
      }
    }
    api: {
      name: 'servicebus'
      id: '/subscriptions/${subscription().subscriptionId}/providers/Microsoft.Web/locations/${Location}/managedApis/servicebus'
      type: 'Microsoft.Web/locations/managedApis'
    }
  }
}

其他服务的配置规则一致：

• 存储账户托管身份连接：parameterValueSet放在properties根层级，values中传入accountName
• Key Vault托管身份连接：parameterValueSet放在properties根层级，values中传入vaultName

调整配置层级后重新执行部署即可解决该报错。
