"LICENSE: copyFile: does not exist (No such file or directory)" (it exists but as a symlink)

[teto]

I've been trying to compile master version of https://github.com/kowainik/co-log/tree/main/co-log-polysemy.
In my cabal.project I have

-- https://input-output-hk.github.io/haskell.nix/tutorials/source-repository-hashes/#handling-git-repositories-in-projects
source-repository-package
  type: git
  location: https://github.com/kowainik/co-log.git
  subdir: co-log-polysemy
  tag: d2c7ad66af4e79c7a8f8d5e6c324ea3ff2739277
  --sha256:1f5sjwkiiqc99n2mghg0i3qhh9d81wp76d2bk4jm4ls2chb069zn

Now the build chokes on a symlink file ("LICENSE"):

note: keeping build directory '/tmp/nix-build-co-log-polysemy-lib-co-log-polysemy-0.0.1.2.drv-0'
error: builder for '/nix/store/15y9id4flhsryxh4dg3pjg2w59xlhznb-co-log-polysemy-lib-co-log-polysemy-0.0.1.2.drv' failed with exit code 1;
       last 10 log lines:

any workaround ? or should I ask upstream to not use symlinks ?

[teto]

I've looked at the build directory and the symlinks are present but because the directory only contains the subdir, the symlinks are dangling. Not sure if that's an issue to solve in the package or if there is any other workaround.

Same problem.
As a hacky workaround, I have fixed it by adding the linked file to the extra-source-files.
