Import of headless.conf.js breaks in Windows due to incorrect pathname

[uglyrobot]

Describe the bug

Using NextJS 14.2 in Windows dev environment. Throws errors that it can't import the config file, and the pathname in the errors is missing the slashes: c:somethingSomethingDirheadless.config.js

I confirmed that merging the configs with withHeadlessConfig() the output is ok, so loading the config in next.config.js is working fine, it's the loading in the package that breaks.

Steps to Reproduce

• Run npm run dev in Windows
• Get compile errors

Thanks for the report.

While I'd typically recommend using WSL2, this should be an easy fix, we just need to make path resolution in withHeadstartWPConfig cross-platform and alongside that include windows to run our test builds in CI.

Did you fix it? I still have the same error

This has been fixed (but not yet released). A separate issue on windows has been opened #902 which seems to be a Next.js issue.
