Fix #839
Ref #718

In the current URLFormat middleware implementation, when rctx (Route Context) is nil, it could lead to unexpected behavior or panic errors in subsequent processing.

To avoid this, I have prioritized not allowing unexpected behavior by implementing error handling for the cases where rctx is missing or nil. Now, instead of failing silently or causing a panic error, the system will return a proper HTTP error response.

This change ensures that the system behaves consistently and avoids potential pitfalls that might arise from missing or improperly initialized rctx.


r.Use(func(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
newCtx := context.WithValue(r.Context(), chi.RouteCtxKey, nil)

Hi @Taaipi,

Thanks for the PR!

It looks like this test cases injects a nil RouteContext down the chain intentionally.

Do you have an example how could this happen in real-world use case? I wonder how is the middleware.URLFormat ever called without chi route context unless we set it to nil explicitly.

Thanks!

I guess based on #718, it'd be better to create a test case with some sub-routers (instead of setting nil). Right?

Are you using middleware.URLFormat outside of chi router?
