Error: Client handler must return a function, got undefined

imports/client-handler.tsx (71:43) @ eval

```

# How to reproduce
Run dev repository in gitpod and open 3007 port

Start by reproducing the error in the dev repository through Gitpod with port 3007 open. Inspect imports/client-handler.tsx around line 71 and trace the deepclientEvalClientHandler call to determine why the client handler resolves to undefined. Done means the reproduction no longer raises the return-type error and the affected behavior is verified.
