Azure 耐用功能错误“当前没有注册任何活动功能！”

完整消息：

Function 'Function1 (Orchestrator)' failed with an error. 
Reason: System.ArgumentException: 
The function 'Function1_GetData' doesn't exist, 
is disabled, or is not an activity function. 
Additional info: No activity functions are currently registered!

[FunctionName("Function1")]
    public static async Task<List<string>> RunOrchestrator([OrchestrationTrigger] DurableOrchestrationContext context) {
        var outputs = new List<string>();

        using (var efContext = new DbContext()) {
            foreach (var s in efContext.Table) {
                var x= await context.CallActivityAsync<bool>("Function2_GetSummonerChanges", s.Id);
                outputs.Add(x.ToString());
            }
        }
        context.ContinueAsNew(null);
        return outputs;
    }

[FunctionName("Function1_GetData")]
    public static bool GetData(long Id) {
        return true;
    }

您没有活动函数“Function2_GetSummonerChanges”的定义

它可能是这样的

[FunctionName("Function2_GetSummonerChanges")]
public static int MyActivityFunction([ActivityTrigger] int id, ILogger log)
{
   // your logic
}
