How to use RequestMultiplayerServerRequest from Azure Functions?

I writed Azure Functions like below

 [FunctionName("RequestServer")]
         public static async Task&lt;dynamic&gt; Run(
             [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
             ILogger log)
         {
    
             FunctionExecutionContext&lt;Dictionary&lt;string, string&gt;&gt; context = JsonConvert.DeserializeObject&lt;FunctionExecutionContext&lt;Dictionary&lt;string, string&gt;&gt;&gt;(await req.ReadAsStringAsync());
             var authContext = new PlayFabAuthenticationContext
             {
                 EntityId = context.TitleAuthenticationContext.Id,
                 EntityToken = context.TitleAuthenticationContext.EntityToken
             };
    
             //GetEntityToken before calling this method
             var requestData = new PlayFab.MultiplayerModels.RequestMultiplayerServerRequest();
             requestData.SessionId = System.Guid.NewGuid().ToString();
             requestData.PreferredRegions = new List&lt;string&gt;() { "EastUs" };
             requestData.BuildId = "xxxx-xxxxx-xxxxxx";
             requestData.AuthenticationContext = authContext;
    
             return await PlayFabMultiplayerAPI.RequestMultiplayerServerAsync(requestData);
         }

I have tested your code, the error said that you must set your TitleId before making the API call. And below is the working code you can refer to set your TitleId.

 [FunctionName("Test")]
         public static async Task&lt;dynamic&gt; Run(
             [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
             ILogger log)
         {
    
             var context = JsonConvert.DeserializeObject&lt;FunctionExecutionContext&lt;dynamic&gt;&gt;(await req.ReadAsStringAsync());
    
             //Set the TitleId.
    
             PlayFabSettings.staticSettings.TitleId = context.TitleAuthenticationContext.Id;
    
              var authContext = new PlayFabAuthenticationContext
              {
                  EntityId = context.TitleAuthenticationContext.Id,
                  EntityToken = context.TitleAuthenticationContext.EntityToken
              };
    
             var requestData = new PlayFab.MultiplayerModels.RequestMultiplayerServerRequest();
              requestData.SessionId = System.Guid.NewGuid().ToString();
              requestData.PreferredRegions = new List&lt;string&gt;() { "EastUs" };
              requestData.BuildId = "e9d78f7c-8df1-4346-aa64-b66dc7079bd3";
              requestData.AuthenticationContext = authContext;
    
             var apiResult = await PlayFabMultiplayerAPI.RequestMultiplayerServerAsync (requestData);
             log.LogDebug(apiResult.Result.ToString());
    
             return new { message=apiResult.Result };            
                
         }
