typescript - The type of the `name` property should be `Path<FieldValues>` - Stack Overflow

I am trying to build FormBuilder component. And have a code like this:

type FormValues = {
  [i: number]: {
    [j: number]: string;
  };
};

export type FormBuilderProps<> = {
  schema: Array<{
    legend: string;
    fields: Array<TF | SF>;
  }>;

  onSubmit: SubmitHandler<FormValues>;
};

export function FormBuilder(props: FormBuilderProps) {
  const { schema, onSubmit } = props;

  const { handleSubmit, control } = useForm({
    resolver: useMemo(() => {
      return zodResolver(
        z.object(
          schema.reduce((result, { fields }, i) => {
            return Object.assign({}, result, {
              [i]: fields.reduce((rules, { schema }, j) => {
                if (schema) {
                  return Object.assign({}, rules, {
                    [j]: schema,
                  });
                }
                return rules;
              }, {}),
            });
          }, {}),
        ),
      );
    }, [schema]),
  });

  return (
    <form
      onSubmit={handleSubmit((data) => {
        return onSubmit(data);
      })}
    >
      {schema.map((fieldset, i) => {
        const {  fields } = fieldset;

        return (
          <fieldset key={`fieldset-${i}`}>
            {fields.map((field, j) => {
              const name = `${i}.${j}`;

              return (
                <Controller
                  control={control}
                  key={`field-${j}`}
                  name={name}
                  render={(renderProps) => {
                    if (field.kind === "text") {
                      const { props } = field;

                      return <input {...renderProps.field} {...props} />;
                    }

                    if (field.kind === "select") {
                      const { props } = field;

                      return <input {...renderProps.field} {...props} />;
                    }

                    throw new Error(`Unsupported kind of field`);
                  }}
                />
              );
            })}
          </fieldset>
        );
      })}

      <input type='submit' />
    </form>
  );
}

The type of the name property should be Path<FieldValues>, but I don't understand at all how to describe this type so that it matches the type of the schema field. So I get the error

Type 'string' is not assignable to type 'Path<TFieldValues>'

controller.d.ts(20, 5): The expected type comes from property 'name' which is declared here on type 'IntrinsicAttributes & { render: ({ field, fieldState, formState, }: { field: ControllerRenderProps<TFieldValues, Path<TFieldValues>>; fieldState: ControllerFieldState; formState: UseFormStateReturn<...>; }) => ReactElement<...>; } & UseControllerProps<...>'

Right now my FormValues ​​type is very abstract and I think that's why I get this error. How should I describe the FormValues ​​type so I don't get this error?
