I've seen these almost same buffer based errors before - with webpack
specifically - and manually creating a symlink helped. I did the same in
this case and the build passes with "Buffer: true"
I've pushed the commit to the same webpack branch
Could you take a look and let me know if it made the situation better/worse?

Thanks and Regards,
Nilesh
