Describe the bug

When we are starting app in dev mode, something goes wrong and nuxt reporting that some package paths are broken. Some paths consist of Array, some are undefined.

Additional context

Package name in logs (@nuxt/ui-templates) appeared because I tried to wrap module resolving function in try catch to determine the broken package. Howerer, it actually didn't help a lot

I can't reproduce with your reproduction.

I confirm that the issues appeared after upgrading to the latest bridge version. When disabling nitro the error goes away, but I still can't preview the home page

[nestle49]

Same error

In case you can't preview the home page, it is related to your user-defined middleware. I honestly have no idea why, but in the end you should have something like this:

// server/middleware/yourMiddleware.ts

import { defineMiddleware } from 'h3'

export default defineMiddleware((req, res, next) => {
  // your code
  next()
}

You could try to omit the next argument as recommended by h3 docs, but for me it made the middleware fire randomly, while I certainly need it on every request

@phoenix-ru I don't have any custom middleware defined but still I can't see the home page
