Help needed

I am trying to add manifest.json and click add to homescreen option. It is always giving me Site cannot be installed: no matching service worker detected. You may need to reload the page, or check that the service worker for the current page also controls the start URL from the manifest.

I am trying this locally and using polymer 2.0

Manifest.json looks something like

{ "name": "fgh", "short_name": "ggg", "theme_color": "#3f51b5", "background_color": "#f8ea48", "display": "standalone", "start_url": "/", "icons": [ { "src": "images/manifest/icon-72x72.png", "sizes": "72x72", "type": "image/png" }, { "src": "images/manifest/icon-96x96.png", "sizes": "96x96", "type": "image/png" }, { "src": "images/manifest/icon-128x128.png", "sizes": "128x128", "type": "image/png" }, { "src": "images/manifest/icon-144x144.png", "sizes": "144x144", "type": "image/png" }, { "src": "images/manifest/icon-152x152.png", "sizes": "152x152", "type": "image/png" }, { "src": "images/manifest/icon-192x192.png", "sizes": "192x192", "type": "image/png" }, { "src": "images/manifest/icon-384x384.png", "sizes": "384x384", "type": "image/png" }, { "src": "images/manifest/icon-512x512.png", "sizes": "512x512", "type": "image/png" } ], "splash_pages": null }

Any help would be appreciated.

Are you generating a service worker from the polymer-cli? Does the service worker get registered in your entrypoint or app shell?

Is the site being served with https:// (or localhost) to allow SW registration? Check Chrome devtools > Application > Service Workers panel to make sure it's registered.
