Cannot authenticate on NixOS via login or npmrc

Current Behavior

I am using fnm to install and manage my node.js and npm version. I set my authentication tokens via direnv. Typically I can add my private registry via the adduser or login command. This command works with (Arch Linux + fnm + direnv) but not from (NixOS + nix-ld + fnm + direnv):

npm adduser --registry https://nexus.XXXXXX/repository/npm-hosted/
npm notice Log in on https://nexus.XXXXXX/repository/npm-hosted/
Username: XXXXXXX
Password:
Email: (this IS public)
⠦

npm error code E401
npm error Unable to authenticate, need: BASIC realm="Sonatype Nexus Repository Manager"
npm error A complete log of this run can be found in: /home/myuser/.npm/_logs/2024-10-01T14_29_32_111Z-debug-0.log

I tried manually setting up my registry and token in .npmrc:

@myorg:registry=https://nexus.XXXXXX/repository/npm-hosted/
//nexus.XXXXXX/repository/npm-hosted/:_authToken=NpmToken.xxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxxxx

Again, this method works as expected with (Arch Linux + fnm + direnv) but not via (NixOS + nix-ld + fnm + direnv). I receive the same error via whoami:

$ npm whoami --registry https://nexus.XXXXXX/repository/npm-hosted/
npm error code E401
npm error Unable to authenticate, need: BASIC realm="Sonatype Nexus Repository Manager"
npm error A complete log of this run can be found in: /home/myuser/.npm/_logs/2024-10-01T15_46_05_297Z-debug-0.log

I can confirm the environment variable is populating so direnv is doing its job:

package.json:

{
  ...
  "name": "myrepo",
  "version": "1.12.21",
  "private": true,
  "workspaces": [
    "packages/*"
  ],
  "scripts": {
    "print": "node -e \"console.log(process.env.NPM_TOKEN)\""
  },
  "dependencies": {
  ...
}

$ NPM_TOKEN=foo npm run print

> myrepo@1.12.21 print
> node -e "console.log(process.env.NPM_TOKEN)"

foo

Expected Behavior

With an appropriately set .npmrc, npm whoami should return successfully.

Steps To Reproduce

  1. In this environment…
configuration.nix 
### snip
  users.users.myuser.packages = with pkgs; [ fnm ];

  programs.mtr.enable = true;

  programs.nix-ld = {
    enable = true;
    libraries = with pkgs; [
      curl
      glib
      icu
      libdrm
      libusb1
      libuuid
      nspr
      nss
      openssl
      stdenv.cc.cc
      zlib
    ];
  };

  home-manager.users.myuser.programs.direnv.enable = true;
### snip
  1. With this config…
.npmrc 
@myorg:registry=https://nexus.XXXXXX/repository/npm-hosted/
//nexus.XXXXXX/repository/npm-hosted/:_authToken=NpmToken.xxxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxxxx
  1. Run…
npm whoami
npm whoami --registry https://nexus.XXXXXX/repository/npm-hosted/
  1. See error…
$ npm whoami
npm error code ENEEDAUTH
