I am trying to run the Lean Report generator locally from a json report downloaded from a run done on QuantConnect and it fails because a loaded option symbol has a null underlying reference and fails at SecurityService.cs line 131
If I look at the json, the option symbols do have the underlying:
"Symbol": {
"Value": "WAG 101016P00025000",
"ID": "WAG 2YPXFKVWULF1I|WAG R735QTJ8XC9X",
"Permtick": "WAG 101016P00025000",
"Underlying": {
"Value": "WAG",
"ID": "WAG R735QTJ8XC9X",
"Permtick": "WAG"
}
}Here is the stack:

Hi Ari,
Please save the result file in a dropbox and share a link to it here so we can reproduce the error. Sharing the backtest would help us reproduce it too.
Best,
