503 error adding API routes

I'm running latest version of all packages and when I try to add API routes per the docs the app blows up with this error:

TypeError: Cannot read properties of undefined (reading 'update')
    at eval (apps/web/src/routeTree.gen.ts:6:46)
...

TypeError: Cannot read properties of undefined (reading 'update')
    at eval (apps/web/src/routeTree.gen.ts:6:46)
...

This occurs immediately after adding

src/routes/api.ts

src/routes/api.ts

per the docs:

import {
  createStartAPIHandler,
  defaultAPIFileRouteHandler,
} from "@tanstack/react-start/api";

export default createStartAPIHandler(defaultAPIFileRouteHandler);

import {
  createStartAPIHandler,
  defaultAPIFileRouteHandler,
} from "@tanstack/react-start/api";

export default createStartAPIHandler(defaultAPIFileRouteHandler);

Adding a basic API route doesn't make any difference. I've tried removing the

routeTree.gen.ts

routeTree.gen.ts

, restarting, etc. but nothing seems to get me past this.
