Type bug: Query's createApi throws annotation error when declaration: true

[colemars]

Error:

The inferred type of this node exceeds the maximum length the compiler will serialize. An explicit type annotation is needed.

Reproduced:

RTK example repo with tsconfig updated to set declaration: true

I was going to create a new issue but it's too related:
fakeBaseQuery with tsconfig's "declaration": true causes:

TS2527: The inferred type of '***' references an inaccessible 'unique symbol' type. A type annotation is necessary.

To reproduce, just use the fakeBaseQuery example from: https://redux-toolkit.js.org/rtk-query/usage-with-typescript with "declaration": true.

Unless the TypeScript team finally gives a good explanation when & why exactly those errors occur and how to prevent them (apart from exporting every single type, which is not a valid solution) I'm sorry there is not much we can do about that.

FYI, I copy-pasted fakeBaseQuery implementation into my own codebase, the error(s) went away and everything compiled, including the auto-generated React hooks. I'll update if anything comes up.

EDIT: I had to also export const _NEVER = /* @__PURE__ */ Symbol() which means I changed it to: export const _NEVER = /* @__PURE__ */ Symbol().
