websocket-driver was not found on deploy - ruby-on-rails

Question

I am trying to update my Rails 5.2.1 app on Heroku and I've got this error.
remote: -----> Installing dependencies
remote: Installing node modules (yarn.lock)
remote: yarn install v1.17.2

Here is my package.json:
{
"name": "kamelot",
"private": true,
"dependencies": {
"#rails/webpacker": "3.5",
"babel-preset-react": "^6.24.1",
"flatpickr": "^4.5.7",
"highcharts": "^7.1.1",
"prop-types": "^15.7.2",
"react": "^16.8.6",
"react-color": "^2.17.3",
"react-dom": "^16.8.6",
"react_ujs": "^2.5.0",
"webpack-cli": "^3.3.4"
},
"devDependencies": {
"webpack-dev-server": "2.11.2"
}
}
I tried adding the node version but that didn't resolve the issue.
This used to work. How can I fix it?
I can't find this file "/tmp/build_545b56879454d397f9a53d8826eeeffb/yarn-error.log"
I did the following
cd tmp
Nothing like build_

Answer 1

For some reason version 0.7.2 of websocket-driver is not published on NPM, though it does exist on GitHub.
I suggest you upgrade to 0.7.3 (or whatever the latest version is when you read this) and redeploy:
yarn upgrade websocket-driver
git add yarn.lock
git commit -m 'Update dependencies'
git push heroku master

Answer 2

Best way for me:
delete package-lock.json
npm i
