Form submit with SolidStart

Hello everyone,

i am following the docs from https://docs.solidjs.com/solid-router/reference/data-apis/action for using a formdata action (server) , but I get the following error.

Can anyone point me to the right direction here?

export const register = action(async (formData: FormData) => {
    "use server";
    
}, "register");

export const register = action(async (formData: FormData) => {
    "use server";
    
}, "register");

export const register = action(async (formData: FormData) => {
    "use server";
    
}, "register");

export const register = action(async (formData: FormData) => {
    "use server";
    
}, "register");

const registerAction = useAction(actionApi.register);

const registerAction = useAction(actionApi.register);

const registerAction = useAction(actionApi.register);

const registerAction = useAction(actionApi.register);

<form class = "grid grid-cols-4 gap-4 w-full" action={registerAction} method="post">

<form class = "grid grid-cols-4 gap-4 w-full" action={registerAction} method="post">

<form class = "grid grid-cols-4 gap-4 w-full" action={registerAction} method="post">

<form class = "grid grid-cols-4 gap-4 w-full" action={registerAction} method="post">

Cheers
