Error: Unable to resolve module `warnOnce` from `/home/rob/Documents/testproject/node_modules/react-native/Libraries/react-native/react-native-implementation.js`: Module `warnOnce` does not exist in the Haste module map

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

Describe what you expected to happen:
Project builds without error

Snack, code example, or link to a repository:

This is a known issue when using haste

#24479
#24065
#23943

I believe it is already solved on master since it is no longer using haste and will probably be out in next patch or v0.61

You can try solutions in linked issues meanwhile, but I came across similar issue, cleared all these caches and had no luck 😒

I start facing this issue after upgrading form RN 60.4 to 61.1.
My workaround is to change metro.config.js to look like this
UPDATE same with RN 0.61.2

const blacklist = require('metro-config/src/defaults/blacklist');

module.exports = {
  resolver: {
    blacklistRE: blacklist([
      /node_modules\/.*\/node_modules\/react-native\/.*/,
    ])
  },
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
};

if you getclient.send error try to add metro yarn add metro
