yo oauth-auth-code-grant-sample

Error - Error oauth-auth-code-grant-sample , primordials is not defined.

My node version is v12.15.0

P.S - i have tried updating gulp version but it does not work.

There might be a problem with node.js of your version and gulp.

What is your exact node and gulp version?
