TS2536: Type '"default"' cannot be used to index type 'Ts'. After upgrading to TS 3.1.1

I just tried upgrading my TypeScript app from TS 3.0.1 to 3.1.1. When compiling it with webpack, having rewiremock as one of our (dev-)dependencies, compilation breaks at this point:

    ERROR in [at-loader] ./node_modules/rewiremock/rewiremock.d.ts:122:66 
        TS2536: Type '"default"' cannot be used to index type 'Ts'.

Interestingly, when I compile with tsc, I do not get this error.

Did not tried TS 3 yet.

I've simplified dts, and trying to understand why it was so complex.
Should work fine with 3.8.0

Yes, works for me! Thanks a lot 🙂
