.NET 8 V4 Azure Function隔离模式CosmosDB连接异常求助

搭建了基于.NET 8 V4版本的Azure Functions隔离模式应用，通过CosmosDB触发器与绑定实现对CosmosDB的数据读写操作。本地环境下，通过local.settings.json配置连接字符串后应用运行正常，但部署到Azure平台后，函数虽能启动运行，却无法与CosmosDB建立通信。已在Azure门户中通过环境变量和连接字符串选项配置对应信息，问题仍未解决，以下是相关代码与配置信息，恳请协助排查：

代码片段 #

public CosmosDBFunction(ILogger<CosmosDBFunction> logger,
    IHttpClientFactory httpClientFactory)
{
    _httpClientFactory = httpClientFactory.CreateClient();
    _logger = logger;
    _cosmosClient = new CosmosClient("AccountEndpoint=<Connection>");
}

[Function(nameof(Function))]
public static async Task<string> RunOrchestrator(
    [OrchestrationTrigger] TaskOrchestrationContext context)
{
    ILogger logger = context.CreateReplaySafeLogger(nameof(CosmosDBFunction));
    logger.LogInformation("----Function Started-----");

    string pagesToLinks = await context.CallActivityAsync<string>(nameof(somefunction));
    string linksToClins = await context.CallActivityAsync<string>(nameof(somefunction));
    string Blinks = await context.CallActivityAsync<string>(nameof(somefunction));

    logger.LogInformation("----Function Finished-----");
    return "Operation Is Completed";
}

[Function(nameof(SomeFunction))]
[CosmosDBOutput(databaseName: "X", containerName: "Y",
      Connection = "ConnectionNameSavedInLocal.Setting.json"
     , CreateIfNotExists = true, PartitionKey = "/dd")]
public async Task<string> ScanLinksAndInsertIntoLinksContainer
    ([ActivityTrigger] string name,
    [CosmosDBInput(
    databaseName:"ss",
    containerName:"pt",
    Connection = "ConnectionNameSavedInLocal.Setting.json"
    )]
    List<todo> todos,
    FunctionContext executionContext){}

Host.json配置 #

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      },
      "enableLiveMetricsFilters": true
    },
    "extensions": {
      "cosmosDB": {
        "connectionMode": "Direct",
        "userAgentSuffix": "MyDesiredUserAgentStamp"
      }
    }
  }
}

local.settings.json配置 #

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",
    "CosmosConnection": "AccountEndpoint=https: <ConnectionString>"
  }
}

Azure门户连接字符串配置 #

[
  {
    "name": "CosmosConnection",
    "value": "AccountEndpoint= 
             <ConnectionString>",
    "type": "DocDb",
    "slotSetting": false
  }
]
