Hi, is there a way to do a Principal lookup in the `security` definition of a ContractRoute or have do be done apart ?

The answer is Yes, BearerAuthSecurity has a constructor that looks like is doing it:
```  constructor(key: RequestContextLens&lt;Any&gt;, lookup: (String) -&gt; Any?, name: String = "bearerAuth") ```
But the problem I got with that is that it requires a &lt;Any&gt;
if I try to use a lens: `val credentials = RequestContextKey.required&lt;Credentials&gt;(contexts)`

I get a:
```Type mismatch.
Required:
RequestContextLens&lt;Any&gt; /* = BiDiLens&lt;Request, Any&gt; */
Found:
RequestContextLens&lt;Credentials&gt; /* = BiDiLens&lt;Request, Credentials&gt; */```
Declaring the Lens as `Any` and then doing an `as`  when using the Lens works.

```val credentials = RequestContextKey.required&lt;Any&gt;(contexts)

...
val handler: HttpHandler = { request -&gt;
    val user = credentials(request) as? Credentials
    ...
}
...

meta {
   ...
   security = BearerAuthSecurity(key = credentials, User::fromJwtClaims)
   ...
}```

Hmmm. Try writing your own Security and seeing if it works. It may require changing.

You may need to override the securotyrenderer as well to get it to render correctly in the openapidocs
