nextjs - 💡(How to fix) Fix Turbopack sourcemap url encoded prevent vscode debugger to work correctly through docker [1 participants]

Link to the code that reproduces this issue

https://github.com/PierreCavalet/turbopack-sourcemap-bug-reproduction

To Reproduce

Everything is provided in the README.md

• clone the repository
• install the stack

./up.sh

Go on both URLs provided in the readme and play with breakpoint. Everything should be working.

comment line 26 in .vscode/launch.json

breakpoint in [locale]/page.tsx should not be working.

Current vs. Expected behavior

I'm using next 16 (16.0.3) and turbopack through docker and docker compose in dev mode.

I've been using next since version 13 and never had any issue making debugger work through docker with webpack, using sourcemapoverrides localRoot & remoteRoot.

however now that next uses turbopack, I cannot find a suitable sourcemapoverrides, because turbopack url encodes the file path, which vscode & cursor does not seem to be able to treat.

      "sourceMapPathOverrides": {
        // Base path mappings
        "/usr/app/frontend/*": "${workspaceFolder}/frontend/*",
        "file:///usr/app/frontend/*": "${workspaceFolder}/frontend/*",

        // Turbopack protocol mappings
        "turbopack:///_N_E/*": "${workspaceFolder}/frontend/*",
        "turbopack:///./*": "${workspaceFolder}/frontend/*",
        "turbopack:///*": "${workspaceFolder}/frontend/*",

        // URL-encoded route segments (Turbopack encodes [segment] as %5Bsegment%5D)
        "file:///usr/app/frontend/app/%5Blocale%5D/*": "${workspaceFolder}/frontend/app/[locale]/*
      },

this is what I'm forced to do, but I cannot do this for everything that has brackets ...

If I disable my hardcodedsource map path override I get

✅
 This breakpoint was initially set in:

/home/xxx/workspace/my-project/frontend/app/[locale]/page.tsx line 17 column 3

❓
 We couldn't find a corresponding source location, but found some other files with the same name:

/home/xxx/workspace/my-project/frontend/app/%5Blocale%5D/page.tsx
If this is the same file, you may need to adjust your build tool to correct the paths.

Current behavior

I need to map every path containing brackets in my launch.json

Expected behavior

It should work without mapping it or turbopack should expose an option to not url encode its sourcemap
