Resolver Type Compatibility

[fjuric]

I'm currently facing an issue with the react-hook-form library and its integration with yup for schema validation. I've encountered the following error: Type 'FieldValues' is not assignable to type 'MakeKeysOptional<TFormValues>'.

Here is codesandbox to a minimal reproduction of the issue.

I would greatly appreciate any insights, suggestions, or solutions from the community. Has anyone else encountered a similar issue, and if so, how did you resolve it?

Thank you in advance for your assistance.

P.S. Interestingly, when using Zod instead of Yup, the error does not occur.

Update: Solved, for solution go to codesandbox.
