Error #1: Route path compilation failed

createUrl() or open() tried to build a URL, but the given params did not satisfy the path pattern.

How to reproduce

import { createRoute } from 'mobx-route';

const userRoute = createRoute('/users/:id');

// `id` is required by the pattern but not provided:
userRoute.createUrl({} as any);
// → console.error: "Error #1: Route path compilation failed"
// → returned URL falls back to `fallbackPath` (or '/')

What the library does

Logs the error (minified in production), then navigates to fallbackPath from the route or routeConfig, or '/'.

Fix

Pass complete params when opening or building links. If params can be missing at runtime, set a safe fallbackPath so users land somewhere sensible instead of a broken URL.

In development, check the logged exception for the exact segment that failed.
