We are trying to upgrade Aspose.Cells (for .NET) to the new released version- v22.2 (the motivation is using the AbstractCalculationEngine).
We had a working test that fails after upgrading to v22.2.
The failure is in GridJsWorkbook.MergeExcelFileFromJson. We used to open this BasicTestToSaveData.zip (583 Bytes) JSON as the JSON input for this method, and we get an exception: System.NullReferenceException: 'Object reference not set to an instance of an object.'
Can you please advice?
