Load License directly from buffer Aspose.PDF for C++

Hi, I an trying to load license from resources using an unsigned char* buffer but it throws the following exception System::ExceptionWrapper<System::Details_NullReferenceException> on second line.

auto m_Arr = MakeArray<uint8_t>(size, data);
auto m_StreamIn = MakeObject<System::IO::MemoryStream>(m_Arr, false);
m_StreamIn->Seek(0, System::IO::SeekOrigin::Begin);
auto m_License = MakeObject<Aspose::Pdf::License>();
m_License->SetLicense(m_StreamIn);

data is unsigned char* containing license content

If i try to write the buffer in a temporary file and then load that file as license using the path works.
I would like to know if there is any solution to load license directly from buffer.
(I am using this version of aspose Downloads ---New-Releases-aspose.pdf-for-c++-19.11 . on 64x)

In Aspose.PDF for C++ 20.3, this code works pretty well on valid license data.

auto ms = System::MakeObject<System::IO::MemoryStream>(System::IO::File::ReadAllBytes(LicenseFilePath)); 
auto lic = System::MakeObject<License>(); 
lic->SetLicense(ms);

There can be possible errors (i.e. NullReferenceException) if stream contains incorrect data. In case you face similar issues, please share your license file in a private message. You can send a private message by clicking over username and pressing Blue Message Button.
