Is there a way to grab a throwed error in "action" function

Hello i have a question. I'm going more in depth into solid. But is there actually a way to grab the error that has been throwed inside an "action" function? i have a function like this ( example ):

export const register = action(async (data: FormData) => {

    const username = data.get("username");
    const password = data.get("password");

    const repeatPassword = data.get("passwordRepeat");

    throw new Error("Not implemented yet");
});

export const register = action(async (data: FormData) => {

    const username = data.get("username");
    const password = data.get("password");

    const repeatPassword = data.get("passwordRepeat");

    throw new Error("Not implemented yet");
});

and this is the html / jsx implementation:

  <Card
      component="form"
      class="w-96"
      action={register}
      method="post"
  >
                {/** --> show some error here <-- **/}

                <input class="border w-full mb-3 rounded-md py-1.5" name="user" type="text" required/>
                <input class="border w-full mb-3 rounded-md py-1.5" name="password" type="password" required/>
                <input class="border w-full mb-3 rounded-md py-1.5" name="passwordRepeat" type="password"
                       required/>
                <Button class="w-full" component="button" type="submit">
                    Register
                </Button>
  </Card>

  <Card
      component="form"
      class="w-96"
      action={register}
      method="post"
  >
                {/** --> show some error here <-- **/}

                <input class="border w-full mb-3 rounded-md py-1.5" name="user" type="text" required/>
                <input class="border w-full mb-3 rounded-md py-1.5" name="password" type="password" required/>
                <input class="border w-full mb-3 rounded-md py-1.5" name="passwordRepeat" type="password"
                       required/>
                <Button class="w-full" component="button" type="submit">
                    Register
                </Button>
  </Card>

I think the idea is to return errors and throw redirects Then use 'useSubmission' to get the value from the action

How would it look like code wise? Like:

export const register = action(async (data: FormData) => {

    const username = data.get("username");
    const password = data.get("password");

    const repeatPassword = data.get("passwordRepeat");

    if(password !== repeatPassword) {
        throw redirect("/register?error=...");
    }
});

export const register = action(async (data: FormData) => {

    const username = data.get("username");
    const password = data.get("password");

    const repeatPassword = data.get("passwordRepeat");

    if(password !== repeatPassword) {
        throw redirect("/register?error=...");
    }
});

but how does the useSubmission now about the action?

   const action = useSubmission(register);

   const action = useSubmission(register);

where do i hook it up?

I'm not exactly sure how it knows but it does Just return new Error(). And then get it from action.result or something
