# X_PWA_PUSH_PAYLOAD_TOO_LARGE

## Means

the push message does not fit one 4096-byte record

## Typical cause

the rendered notification (title, body, actions, url) serialises past the 3993 bytes RFC 8291 leaves for plaintext in one record

## Fix

`url: '/posts/1'` — send a path to the content and shorten the catalog strings, never the content itself
