I'm trying to bundle helmet with rollup-plugin-typescript2, but I keep getting this error, is it related directly to helmet or is this a ts/rpt2 issue?

I'm not sure, but I assume this is an issue with the Rollup plugin. Helmet's type definitions look correct to me, and seem to be working well for others.

I'm going to close this issue, but let me know if that's wrong and I can reopen.
