# E-AUTH-004

> Retired: doctor no longer mints an actAs credential or verifies it against your host.

```text retired theme={null}
E-AUTH-004 — retired, doctor no longer emits this code
```

`error_code: E-AUTH-004` · `status: retired`

## What you're seeing

Nothing: `npx vendo doctor` cannot print this code anymore. You are reading
it from an older run's output, or a saved report.

## Why

This code fired when doctor minted an away credential through your `actAs`
seam and your principal resolver refused it. Doctor only reads files now, so
it mints nothing and verifies nothing.

## The fix

The seam can still be broken, and you check it yourself now. Trigger one
real away action and read the dev server log; a broken mint or a refused
credential shows up there with its own error.

Check `createVendo({ auth })` (or a hand-wired `actAs`), the verifier
middleware on your host API, and the host's principal resolver. For Clerk or
Auth0, confirm `VENDO_AWAY_TOKEN_SECRET` is the same value on both sides.
See [Host auth](/production/auth) for how the three auth seams fit together.
