This is shown in VSCode if tsconfig.json contains skipLibCheck: false.

@1EDExg0ffyXfTEqdIUAYNZGnCeajIxMWd2vaQeP Could you provide more informations? (the createRouter call, where the TS error is reported exactly).
The example app on this repository use skipLibCheck: false and don't suffer from this issue.

Steps to reproduce

  1. Clone this repo
  2. execute yarn install && yarn build
  3. open dist/createRouter.d.ts in VSCode4
  4. This error message appears in the "Poblem" tab

Does that help?

@1EDExg0ffyXfTEqdIUAYNZGnCeajIxMWd2vaQeP Ok, I though it happened when using createRouter in a particular way. Didn't get your point correctly.

It's fixed it in v1.3.3. When generating type declarations, TS "flatten" the types for concision. And here, it failed (probably because of the complexity of this type). Extracting this part as a GetCreateURLFns type function solve this issue.

Thanks for reporting this!
