Next.js getStaticProps fails to fetch to connected database (App Platform)

I’ve implemented getStaticProps for my next.js application which works perfectly locally, but fails on the app platform. The build will hang indefinitely on “pool.query” to the connected database when creating the static images, and will be killed and rebuilt 3 times before failing.

After a lot of testing, I’ve discovered my build works on the app platform when it’s connected to a 3rd party database. I don’t understand why this is the case as my current build on the app platform and my local build can use the connected db.

import { FusionDex } from "../components/components";
import { wrapper, addInitialStore } from "../store/store";
import getInitialStore from "./api/initialStore";

export default function Home() {

  return <>
    <FusionDex />

export const getStaticProps = wrapper.getStaticProps(store => async (props) => {

  try {
    let initialStore = await getInitialStore();


  } catch (error) {
    console.error('Error executing database query:', error);

Hi there,

Indeed, during the build process, your app would not have access to the Managed Database cluster in case that you have the trusted sources enabled.

If possible, what I would suggest is that if you have a migrations step, you could move that step from the build process to the deployment process.

The benefit of doing this is that, if your build is successful and the changes to the database are executed, but the deployment fails, then you might end up with the new database schema but with your old codebase which might not be backward compatible.

If this is not applicable in your case, what you could do is to disable the trusted sources so that the database will be accessible during the build process.

Let me know how it goes!
