# `deployable.target_unknown`

Deployable's target isn't one Jadpo builds for.

Area 14, [Tooling](../topics/tooling.md); not declinable; the next step is usually the agent's.

A deployable is built for `Target.native` or `Target.wasm`; Workers is
where WebAssembly runs:

```jadpo
application {
    deployables: {
        kiosk: {
            serves: [main]
            target: Target.workers
        }
    }
}
```

```text
error: `Target.workers` isn't a target
 --> app.jadpo:5:21
  |
5 |             target: Target.workers
  |                     ^^^^^^^^^^^^^^ not a `Target`
  reason: A deployable is built for `Target.native`, a server, or `Target.wasm`, WebAssembly on Cloudflare Workers. Did you mean `Target.wasm`?
  next: Use `Target.wasm` instead (agent)
