Permission issues with dawn submodules

[Ashwin Bhat]

Apologies if this common knowledge but does anyone know how to get around this error while shallow cloning dawn?

Cloning into 'F:/source/WebGPU/dawn/third_party/angle/third_party/gles1_conform'...
remote: PERMISSION_DENIED: The caller does not have permission
remote: [type.googleapis.com/google.rpc.RequestInfo]
remote: request_id: "a2f1d9042ff24d6988c7e6de059a847f"
fatal: Authentication failed for 'https://chrome-internal.googlesource.com/angle/es-cts/'
fatal: clone of 'https://chrome-internal.googlesource.com/angle/es-cts' into submodule path 'F:/source/WebGPU/dawn/third_party/angle/third_party/gles1_conform' failed
Failed to clone 'third_party/gles1_conform' a second time, aborting
fatal: Failed to recurse into submodule path 'third_party/angle'

Thanks

I believe that happens if you use `git submodule update` or `git clone --recurse-submodules` or similar commands. That's not supported in Dawn. Instead, clone Dawn without any submodules, then use either `tools/fetch_dawn_dependencies.py` or `gclient sync` (or if you are using a CMake build, you can just set `DAWN_FETCH_DEPENDENCIES` which calls `fetch_dawn_dependencies.py` automatically).

HTH,

BTW, there are other things you'll probably run into. These are (hopefully) all described in the build documentation: https://dawn.googlesource.com/dawn/+/refs/heads/main/docs/building.md
