ERROR Error: Uncaught (in promise): TypeError: Failed to register a ServiceWorker
We have a PWA that has been working fine for a long time, but now it seems the app is having trouble registering the service worker. We are using Angular 7 and the ngsw-worker.js is not output in the build folder. The error in the console is:
ERROR Error: Uncaught (in promise): TypeError: Failed to register a ServiceWorker: A bad HTTP response code (404) was received when fetching the script.
We are registering the service worker in core.module.ts like this:
ServiceWorkerModule.register('ngsw-worker.js', { enabled: environment.production })
Our ngsw-config.json look like this:
{
"index": "/index.html",
"assetGroups": [
{
"name": "app",
"installMode": "prefetch",
"resources": {
"files": [
"/favicon.ico",
"/index.html",
"/*.css",
"/*.js"
]
}
}, {
"name": "assets",
"installMode": "lazy",
"updateMode": "prefetch",
"resources": {
"files": [
"/assets/**"
]
}
}
]
}
Is the ngsw-worker.js file supposed to be output explicitly in the dist folder, or is it part of the bundle?
