Does required<string>('Please enter your name.') fix it?

It is the <Field>'s child function that throws Typscript warnings:

field:FieldStore, props:FieldElementProps

I need more of your code or a reproduction on Stackblitz. What framework are you using?

I"m using SolidJS. Typescript does not like FieldStore or FieldElementProps as types. The both have an underline in red in VisualStudioCode. I just set them both to :any to hide the warnings.

Feel free to create a reproduction using this template: https://stackblitz.com/edit/modular-forms-solid?file=src/routes/login.tsx

I'll have to investigate further since some components do not show the Typescript warning, but some do. It may have to do with the <Form element being in a separate component instead of in the same component as the <Field elements. I have a component to render the start of the <Form, and then another component which renders the <Field components.
