# X_PWA_PUSH_UNCONFIGURED

## Means

push is not configured in this process

## Typical cause

`pushSubscribe()`, `pushUnsubscribe()` or `webPush()` ran in a process whose boot installed no Web Push runtime: `pwa.push` is false, or `pwa.enabled` is

## Fix

`pwa: { enabled: true, push: true, vapid: { subject: 'mailto:ops@example.com' } }` in `app.config.ts`; a test calls `installWebPush({ store, keys, subject })` first
