Absolute Windows paths are handled as invalid URL path in ESM import() #34765
Description
- Version: v14.8v0
- Platform: Windows
- Subsystem:
Related: #31710
What steps will reproduce the bug?
Windows paths are interpreted as invalid file URL. In Linux and Mac, the issue can't be reproduced.
Fail
await import("D:\repositories\fastify-autoload\routes\hello.mjs")Works
await import(url.pathToFileURL("D:\repositories\fastify-autoload\routes\hello.mjs").href)Root cause
What is the expected behavior?
Interpret windows paths as valid URL paths so we can provide consistent cross-platform behaviour.
What do you see instead?
