Our project uses react-router v3.
Run the server in dev mode and got an error
You have provided a history object created with history v4.x or v2.x and earlier.
This version of React Router is only compatible with v3 history objects.
Please change to history v3.x.
I got the error even with no any mdx files created.
Only removing react-router v3 from dependencies resolves the issue.
I'll release some new version this week with react-router inside the bundle of docz. It's already done, but I need to release... I think that this can fix your issue 馃檹
Confirm, it works with react-router v3 in just-released docz v0.11.1
