> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# decodeCatchUpEvent

```typescript
decodeCatchUpEvent(bytes: Uint8Array): CatchUpEvent | undefined
```

Decode one binary protobuf `CatchUpEventsResponse` frame into the same
high-level event shape the v1 `events.catchUp()` stream produced.

Heartbeats, sequence-only frames, and frames without a recognized event
payload return `undefined`. Errors from the generated protobuf decoder
propagate to the caller.

## Parameters

<ResponseField name={"bytes"} type={"Uint8Array"} required />

## Returns

<code>[CatchUpEvent](/docs/reference/stable/advanced-imessage/grpc/types/CatchUpEvent){" | undefined"}</code>
