Azure Function TimeTrigger重复触发问题求助

问题现象 #

我有一个名为POEditorTranslations的Azure Function，TimerTrigger配置的Cron表达式为：

* */10 * * * *

最初它是异步函数public static async Task POEditorTranslations...，调用多个外部API并等待响应时，发现它未按10分钟间隔执行，而是反复触发。改成仅输出日志的基础同步函数后，问题仍然存在！

函数代码 #

[FunctionName("POEditorTranslations")]
public static void POEditorTranslations([TimerTrigger("%POEditorSchedule%")] TimerInfo myTimer, ILogger log, Microsoft.Azure.WebJobs.ExecutionContext context)
{
    IConfigurationRoot config = new ConfigurationBuilder()
                .SetBasePath(context.FunctionAppDirectory)
                .AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
                .AddEnvironmentVariables()
                .Build();

    log.LogInformation($"POEditorTranslations TESTING function executed at: {DateTime.Now}, POEditorSchedule: {config.GetValue<string>("POEditorSchedule")}");

}

关键细节 #

• 本地Visual Studio运行正常，本地存在local.settings.json文件，但Azure环境中无该文件。
• 日志显示配置项POEditorSchedule的值正确，但触发间隔仅约1秒，日志片段如下：

有人建议在Azure门户使用环境变量替代配置，但找不到对应的菜单：
