Strange error on submitting.

When I use the api to submit a run, it returns the following error.

SpeedrunComSharp.APIException was unhandled HResult=-2147024809 Message=There are problems with your submitted run, see the errors attached. Source=SpeedrunComSharp StackTrace: at SpeedrunComSharp.SpeedrunComClient.DoPostRequest(Uri uri, String postBody) in C:\Users\jakef_000\Downloads\SpeedrunComSharp-master\SpeedrunComSharp-master\SpeedrunComSharp\SpeedrunComClient.cs:line 177 at System.Dynamic.UpdateDelegates.UpdateAndExecute3[T0,T1,T2,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2) at SpeedrunComSharp.RunsClient.Submit(String categoryId, String platformId, String levelId, Nullable1 date, String regionId, Nullable1 realTime, Nullable1 realTimeWithoutLoads, Nullable1 gameTime, Nullable1 emulated, Uri videoUri, String comment, Uri splitsIOUri, IEnumerable1 variables, Nullable1 verify, Boolean simulateSubmitting) in C:\Users\jakef_000\Downloads\SpeedrunComSharp-master\SpeedrunComSharp-master\SpeedrunComSharp\Runs\RunsClient.cs:line 217

What does this mean, and how can I fix?

Start at SpeedrunComSharp.RunsClient.Submit in SpeedrunComSharp/Runs/RunsClient.cs:217, then inspect SpeedrunComClient.DoPostRequest in SpeedrunComSharp/SpeedrunComClient.cs:177. Check the APIException's attached errors and the submitted parameters to determine which input the API rejects. Done means identifying the invalid submission data and documenting or reproducing the fix.
