Unable to open Excel file. Error: Key cannot be null. Parameter name: key

I am getting the following error when I try to open a few files downloaded from Google Vault file in Aspose.Cells.

error Key cannot be null.
Parameter name: key

All the failing files have Pivot tables. The same file opens without any issue if I open it in MS Excel and save without making any changes.

Can you please help me get past this?

Thanks

Bharat
