NodeJS v12-v15 has been merged upstream and should be part of SWIG 4.1 ; we should direct people to use that release instead of relying on our fork (which will continue only for TC integration purposes).

can I work on this issue?

Unfortunately, there is nothing to do here until SWIG does a 4.1 release.

However, if you are looking into hacking, you could have a look at #3317
