Cannot use a simple third-party union type in typed API params

[CodeWithOz]

Steps to reproduce:

• create new encore project
• install countries-list
• import TCountryCode type from countries list: import { TCountryCode } from "countries-list"
• use it as the type of a field in an encore endpoint param: api<{ country: TCountryCode }, void>(...).
• run encore: encore run

Error:

error: object not found: TCountryCode
  --> /path/to/app.ts:12:10
   |
12 | import { TCountryCode } from "countries-list";
   |          ^^^^^^^^^^^^


error: unknown identifier
  --> /path/to/app.ts:24:29
   |
24 |   async (params: { country: TCountryCode }): Promise<{ success: boolean }> => {
   | 

Worth noting that the TCountryCode type is a very basic union type that's exported normally from the index.d.ts file. Surprising to say the least that this would raise an error with encore. Perhaps another case of incomplete typescript support, similar to what's happening in #1669 ?

No, the actual type definition is here: https://github.com/annexare/Countries/blob/cc382a4045cc7ca1ecd4c479de402dee1ba28929/packages/countries/src/types.ts#L6

Which is a more complex definition using keyof typeof:

export type TCountryCode = keyof typeof countries

@eandre I see! Thanks for clarifying. So does that mean it is indeed the same typescript support limitation that causes the problem in the linked issue?

@CodeWithOz Could you try upgrading to latest encore version and see if that resolves the issue? we recently have made some improvements to the type resolve that would cause this error. The latest version is v1.48.10
