I have the following server component

"use server";
import { Suspense } from "react";

import { getAutoMixTemplates } from "@/app/actions/autoTemplates/actions";
import AutoTemplatesTable from "./autoTemplatesTable";
export default async function AutoTemplate() {
  const templates = await getAutoMixTemplates();
  return (
    <div>
      <Suspense>
        <AutoTemplatesTable templatesJSON={JSON.stringify(templates)} />
      </Suspense>
    </div>
  );
}

with the following action

export const getAutoMixTemplates = async () => {
  const admin = await initAdmin();
  const db = admin.firestore();
  const templates = await db.collection("autoMixTemplates").get();
  return templates.docs.map((doc) => {
    const data = doc.data();
    return {
      ...data,
      _firestore_id: doc.id,
    };
  });
};

on build i get the error in the picture, why?
I tried to read what it says on that docs/messages/prerender-error, but I don't see how it's related to my code 🤔 if I comment the function getAutoMixTemplates, it works
