declaration-bundler-webpack-plugin Unhandled rejection TypeError: Cannot read property 'split' of undefined

[rupeshtiwari]

Hi I am not sure where is the github location for declaration-bundler-webpack-plugin plugin.
However I saw there is an closed ticket in this repository related to this issue. Which is not yet resolved though people gave their own plugin code which are working solution and solves the issue. However, I see the official plugin version "declaration-bundler-webpack-plugin": "^1.0.3", is still not working it is keep failing for the same error. I guess the fix is not yet merged ? Hence I am opening new issue.

Expected Behaviour

create bundle.d.ts

Actual Behaviour

throwing error Unhandled rejection TypeError: Cannot read property 'split' of undefined

I'm going to close this as there is nothing to do to ts-loader I think. The issue is with "declaration-bundler-webpack-plugin"

Hi @johnnyreilly
Thanks to point out this however I am curious to know where exactly the "declaration-bundler-webpack-plugin" project lives in github ? So that I can create this issue there only.
