Azure函数的Azure Cosmos DB输入绑定不起作用

Question

{
  "bindings": [
    {
      "authLevel": "function",
      "type": "httpTrigger",
      "direction": "in",
      "name": "Request",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "type": "http",
      "direction": "out",
      "name": "Response"
    },
    {
      "name": "bookmark",
      "direction": "in",
      "type": "cosmosDB",
      "databaseName": "func-io-learn-db",
      "collectionName": "Bookmarks",
      "connectionStringSetting": "learn_DOCUMENTDB",
      "id": "{id}",
      "partitionKey": "{id}",
      "sqlQuery": ""
    }
  ]
}

在app服务中有一个learn_DOCUMENTDB配置设置，它具有到cosmos db实例的有效连接字符串（是自动创建的）。

错误日志条目表示：

无法将CosmosDB绑定到类型“System.String”。可能的原因：1）试图绑定到“Microsoft.Azure.Documents.Client.DocumentClient,Microsoft.Azure.DocumentDB.Core,Version=2.9.2.0,Culture=Neutrace，PublicKeyToken=31BF3856AD364E35”，但用户类型assembly为“System.String,System.Private.Corelib,Version=4.0.0.0,Culture=Neutrace，PublicKeyToken=7CEC85D7BEA7798E”。

我是不是做错了什么？

我也遇到了同样的问题，发现新UI生成的绑定与旧UI不同。

新UI：

{
  "name": "bookmark",
  "direction": "in",
  "type": "cosmosDB",
  "databaseName": "func-io-learn-db",
  "collectionName": "Bookmarks",
  "connectionStringSetting": "learn-0088a129-899f-4d18-b4db-5fa74daf1cc3_DOCUMENTDB",
  "id": "{id}",
  "partitionKey": "{id}",
  "sqlQuery": ""
}

旧UI：

{
  "type": "cosmosDB",
  "name": "bookmark",
  "databaseName": "func-io-learn-db",
  "collectionName": "Bookmarks",
  "connectionStringSetting": "learn-0088a129-899f-4d18-b4db-5fa74daf1cc3_DOCUMENTDB",
  "id": "{id}",
  "partitionKey": "{id}",
  "direction": "in"
}

"sqlQuery": ""
