azure function java CosmosDBTrigger-input and @SignalROutput-output, Error :Cannot create Collection Information

Question

我已经用占位符替换了安全数据

本地运行以及部署后出错 -

Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.<Function-Name>'. Microsoft.Azure.WebJobs.Extensions.CosmosDB: Cannot create Collection Information for <Collection-Name> in database <Database-Name> with lease <Lease-Collection-Name> in database <Database-Name> :

local.settings.json 文件 -

}

代码-

@FunctionName("Notify-Update")
    public void notifyDBUpdate(
            @CosmosDBTrigger(name = "dataInput",
                    databaseName = "demo",
                    collectionName = "bagi",
                    leaseDatabaseName = "demo",
                    leaseCollectionName = "leasebagi",
                    createLeaseCollectionIfNotExists = true,
                    connectionStringSetting = "AzureCosmosDBConnection")
                    String document,
            @SignalROutput(name = "dataOutput", hubName = "chat", connectionStringSetting = "AzureSignalRConnectionString") OutputBinding<String> dataOutput,
            final ExecutionContext context) {

        context.getLogger().info("Java CosmosDB Notification trigger processed a request: " + document);

集合和数据库已经创建，但我还没有创建租约集合。

我正在使用 cosmos db、signalr 和 azure 函数开发实时应用程序，但我已经被这个错误困扰了很长一段时间。

您似乎正在使用 Mongo 帐户（您的端点是 <Azure-Cosmos-DB-Account>.mongo.cosmos.azure.com）。

根据 documentation:

Azure Cosmos DB bindings are only supported for use with the SQL API.
