Workbox.core.clientsClaim is not a function

[claudioviola]

Hello guys!
I activate the serviceWorker.register() in my project.
I'm running the build and then I run serve -s build

When I use chrome to connect to localhost:5000 I see this error in the console and my service worker is not registered and in application tab I see that service worker in not installed.

workbox.core.clientsClaim is not a function at service-worker.js:26

This is my config project

"dependencies": {
    "@ionic/react": "^0.0.5",
    "axios": "^0.18.0",
    "dotenv": "^6.2.0",
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-router": "^5.0.0",
    "react-router-dom": "^5.0.0",
    "react-scripts": "3.0.1",
    "use-react-router": "^1.0.5"
  },

yarn 1.7.0
npm 6.1.0

I don't know if it is a bug or just my configuration is failing...

I printed in console the workbobox.core object

Thanks for support

Hi @claudioviola, thanks for raising this. Are you able to provide a repository with a reproduction of this issue for us to take a look at?

Hi @mrmckeb many thanks for the support

Sorry about that but I can't provide any repo cause I created another one from scratch and it worked perfectly.

Basically I faced that issue when yesterday I tried to upgrade my project from react-script 2.0.8 to react-script 3.0.1
Anyway the two projects had same content in src and public folders.

Might be correlated to yarn, npm, node modules?

It's possible... out of interest, have you tried this?

• Delete package-lock.json.
• Delete node_modules folder.
• Run npm i.

I didn't it... but could be the reason

@claudioviola what's the output of $ cat node_modules/workbox-core/package.json | grep version?
