Neynar will throw undefined type error if billing expires

[christopherwxyz]

Describe the bug

If a user leverages Neynar middleware and has not paid Neynar for the service, the frame request will throw an undefined type error. It's difficult to debug this in production as the error occurs in the middleware, however running locally you can throw it with resolution.

TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))
    at eval (webpack-internal:///(rsc)/../../node_modules/frog/_lib/middlewares/neynar.js:36:28)
