# E-WIRE-001

> Doctor's Express check found no createVendo server wiring, so the wire never mounted.

```text wiring/express-server theme={null}
broken: Express server is not wired with createVendo from @vendoai/vendo/server
```

`check: wiring/express-server` · `error_code: E-WIRE-001` · `doctor exits: 1`

## What you're seeing

`npx vendo doctor` fails before it can probe anything live. On an Express
host, this is the first check doctor runs, so nothing downstream even gets a
chance to pass.

## Why

Doctor scanned the repo's source files for a module that imports
`createVendo` from `@vendoai/vendo/server` and calls it. It found none. The
server-side half of the wire was never written, or it imports from the wrong
specifier.

## The fix

Compose the wire in a small server module and mount it on your Express app.

```ts vendo/server.ts theme={null}
import { createVendo } from "@vendoai/vendo/server";
import { anthropic } from "@ai-sdk/anthropic";

export const vendo = createVendo({
  models: { default: anthropic("claude-sonnet-4-6") },
});
```

```ts app.ts {2,5} theme={null}
import express from "express";
import { vendo } from "./vendo/server.js";

const app = express();
app.use("/api/vendo", vendo.express());
```

If you already have a composition, confirm it imports from
`@vendoai/vendo/server` and calls `createVendo({...})` rather than a stale or
misspelled path. Re-run `npx vendo doctor` once the mount is in place.
