[Error] 'Permute Two' is missing in the class attribute

[Dhilip-Palanisamy]

I am getting the below error when I export the Unity project for the Android platform (Unity 2019.3.*).

'Permute Two' is missing in the class attribute 'Extension of Native Class!'

FYI, I have followed all the platform specific instructions from your README.md file. The error is being thrown from the Build.cs file.

Can you please help me to resolve this issue?

Thanks!
