'C:\plat\nf\.next\server\chunks\ssr\[externals]_node:buffer_00e2e67a._.js'
->
'C:\plat\nf\.next\standalone\.next\server\chunks\ssr\[externals]_node:buffer_00e2e67a._.js'

Link to the code that reproduces this issue

https://github.com/example/sorry

To Reproduce

build output standalone

Current vs. Expected behavior

I found that the main problem is the name of the file has a ":" symbol, Result fs copy method failed

The follow name is not correct in Windows

"D:\a\d\dist\server\chunks[externals]node:async_hooks_b485b2a4..js'"

TL;DR

  • Remove or replace the colon (:) symbol from the file name to resolve the copy file error.

Guidance

  • Verify that the issue is indeed caused by the colon (:) symbol in the file name by attempting to copy a file with a similar name but without the colon.
  • Check the code that generates the file name to see if it can be modified to avoid using the colon symbol.
  • Consider using a different character or encoding to represent the colon symbol in the file name, if it is necessary for the application's functionality.
  • Test the application on a different operating system, such as Linux or macOS, to see if the issue is specific to Windows.

Example

  • No code snippet is provided as the issue does not imply a specific code change.

Notes

  • The issue seems to be specific to Windows, as the colon symbol is not allowed in file names on this operating system.
  • The solution may require changes to the code that generates the file name or the use of a different character or encoding.

Recommendation

  • Apply workaround: Remove or replace the colon (:) symbol from the file name, as this is a simple and effective solution to resolve the copy file error.
