Web SDK is not working and I am getting the "Pushwoosh init failed DOMException" error

Question:

I can not get the subscription pop-up in my browser due to the "Pushwoosh init failed DOMException" error.

Answer:

The most common scenario for this error to appear is the mismatch between the versions of Web SDK and the Service Worker.

In order to avoid this error you can:

1. Install the npm package and get the SW from this package

https://www.pushwoosh.com/platform-docs/pushwoosh-sdk/web-push-notifications/web-push-sdk-3.0#install-from-npm

2. Get both: the SDK and the SW from the CDN. In this case, your website will always receive the latest versions automatically.
