Alternative GBS Runs Energy Analysis

Hello everyone, I run an Energy Analysis from Revit and GBS creates the base run and another 300+ alternative runs, but when I load the results in my Dynamo flow, the “GetRunIds” node works properly and see all the runs, but the “LoadAnalysisResults” retrieve me only the “base run” out from the “ParametricRunIds” output. The other alternative runs retrive me “null” and an “internal 500 server error”. Someone can help me please??
