# STORAGE_INVALID_BYTES

**Storage input bytes empty or invalid**

## What happened

An upload was attempted with an empty buffer, a non-buffer value, or bytes that exceed the per-upload size cap.

## How to fix

Verify the bytes are non-empty and within size limits before calling `Storage.upload(...)`. For files, use `readFileSync` + length check.

## Example

```ts
import { readFileSync } from "node:fs";
const bytes = readFileSync(path);
if (bytes.length === 0) throw new Error("empty");
```
