'ERR_INVALID_URL' error when deploying NextJS app that uses getServerSideProps()

Questions / Help
1

Hi, I’ve modified a page in my NextJS app to use getServerSideProps():

export async function getServerSideProps() {
  const helpers = createServerSideHelpers({
    router: databaseRouter,
    ctx: {},
    transformer: SuperJSON,
  });

  await helpers.getAllOrganizations.prefetch();
  await helpers.getAllContacts.prefetch();
  
  return {
    props: {
      trpcState: helpers.dehydrate(),
    },
  };
}

npm run build completes without issues locally but when I run fly deploy I get the error

Error: failed to fetch an image or build from source: error building: failed to solve: executor failed running [/bin/sh -c npm run build]: exit code: 1

To fix this error, are there additional configurations I need to make when calling getServerSideProps() in a project deployed to fly.io? Thank you.

Is the postgres url here valid?

Yes, it seems that for NextJS if I use getServerSideProps() I would need to pass in the postgres database url in build time. The build worked when I passed in the database url in the Dockerfile, so the issue has now moved to this post:
