Action Error : Output is too short

[Inalegwu]

Are you using the latest version of this library?

• I verified that the issue exists in the latest next-safe-action release

Is there an existing issue for this?

• I have searched the existing issues and found nothing that matches

Describe the bug

I found that the action errors when trying to return a redirect from an action, while trying to run an authentication flow in a project. I assume this isn't intended functionality as it isn't described anywhere in the docs.

Reproduction steps

1. create an action that ends in a redirect

export const signup = action(signupSchema, async (input) => {
  const userExists = await db.query.users.findFirst({
    where: (user, { eq }) => eq(user.email, input.email),
  });

  if (userExists) {
    throw new Error("This email is already in use, Please try again");
  }

  const passwordHash = await argon.hash(input.password);

  const userId = generateIdFromEntropySize(10);

  await db.insert(users).values({
    id: userId,
    hashedPassword: passwordHash,
    email: input.email,
  });

  const session = await lucia.createSession(userId, {});
  const sessionCookie = lucia.createSessionCookie(session.id);

  cookies().set(
    sessionCookie.name,
    sessionCookie.value,
    sessionCookie.attributes,
  );

  return redirect("/dashboard");
});

2. attempt running said action
3. Result output is

Action error: output is too short

Expected behavior

On successful action run, the redirect should be run.

I'm not sure this is related to next-safe-action. Action error: default prefix just means that an error occurred on the server.
Are you sure that the redirect function is reached while executing the action? If this is the case, please provide a link to a minimal reproduction repo/Stackblitz env, thanks!

Sorry for the false positive. It was infact an error on my part. Thanks for the advice though, it did point me in the right direction
