Any fix for this?

I faced a similar issue, and was able to get past the conflict based on this post: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/36161#issuecomment-571295417

I'm not sure what the root cause is about, and who (koa-router, or koa-passport and other middleware authors) should be fixing this though.
