Path parameter not accessible when using app.onError()

[justinwride]

What version of Hono are you using?

3.8.0

What runtime/platform is your app running on?

Cloudflare Workers

What steps can reproduce the bug?

When using app.onError() within a nested route, the path parameters are not accessible.

c.req.param('assignmentId') does not work when app.onError(err, c) is in the nested route file

index.js
routes/example.js

See this project for example: https://github.com/justinwride/hono-path

What is the expected behavior?

I expect to access the path parameter for the route /assignments/:assignmentId? using c.req.param('assignmentId')

What do you see instead?

Instead, c.req.param('assignmentId') is undefined

Additional information

It works if app.onError() is put in index.js, but not if it is used in routes/example.js.

I have been experimenting with Hono and enjoy the simplicity and speed. I'm the CTO of an ed-tech company and hope to use it more in our tech stack.
