Getting TypeScript errors when invoking a server action with the action prop

[adamchipperfield]

Summary

I'm trying out the (experimental) Server Actions. When I use the form element's action prop to invoke a server action, TypeScript doesn't like it (understandably, because I'm passing a function when it's expecting a string).

Does anyone know how I can extend the type of the form to allow functions?

I guess you've already tried type for form as FormData?
