TypeError on endpoints with fresh react project

Hi! This is likely user error, I'm not too experienced with NodeJS.

I get this error when trying to access a dynamic endpoint. Interestingly, this doesn't happen on a fresh project with only manifest. So yeah, probably my fault. 😅 Minimum reproduction: 
npx create-react-app@latest test
npx add-manifest
npx create-react-app@latest test
npx add-manifest
added to backend.yml: 
endpoints:
  test:
    path: /test
    handler: test
    method: GET
endpoints:
  test:
    path: /test
    handler: test
    method: GET
manifest/handlers/test.js: 
module.exports = async (req, res) => {
  res.json({ message: 'Hello world from my new endpoint!' })
}
module.exports = async (req, res) => {
  res.json({ message: 'Hello world from my new endpoint!' })
}
node/npm: 
PS C:\Programming\Source\Web\test> node -v
v24.2.0
PS C:\Programming\Source\Web\test> npm -v
11.4.2
PS C:\Programming\Source\Web\test> node -v
v24.2.0
PS C:\Programming\Source\Web\test> npm -v

Hello @Ergo thank you so much for reporting that issue I could reproduce it on Windows + Node 24 and created a patch that fixes this issue. Indeed the path-to-regexp package is not present on that configuration so I had to import it specifically. You can just set the manifest version to 4.12.3 by typing npm i manifest@latest and it should work now ! https://github.com/mnfst/manifest/releases/tag/manifest%404.12.3
GitHub
Release manifest@4.12.3 · mnfst/manifest
Patch Changes c74b428: fixed path error on windows with handler files, thanks @akvgergo
