Bundle errors when setting up react-native in monorepo

I'm having some issues setting up a new react-native project inside a yarn monorepo with workspaces. My root package.json looks like:

{
  "name": "mono-repo",
  "workspaces": {
    "packages": [
      "web-app",
      "utils",
      "mobile-app"
    ],
    "nohoist": [
      "**/jest",
      "**/jest/**",
      "**/mocha",
      "**/mocha/**",
      "**/react-native",
      "**/react-native/**"
    ]
  },

When i run yarn run-ios the build succeeds but I get bundler errors:

bundling failed: Error: Unable to resolve module `bugsnag-react-native` from `index.js`: bugsnag-react-native could not be found within the project or in these directories:
  ../node_modules

the bugsnag-react-native folder does exist in the root node_modules

Does anyone have any idea what might be happening here / how to fix it?

I'm using yarn version 1.19.0
