Shopify PostgreSQL Session Storage Doesn't Work

Question

I'm working to set up PostgresSQL Session Storage for my Shopify app using the direct Shopify documentation

They say to set up Session Storage like so:

import Shopify from '@shopify/shopify-api';

Shopify.Context.initialize({
  SESSION_STORAGE: new Shopify.Auth.Session.PostgreSQLSessionStorage("postgres://username:password@host/database"),
  ...
});

// OR

Shopify.Context.initialize({
  SESSION_STORAGE: Shopify.Auth.Session.PostgreSQLSessionStorage.withCredentials(
    "host.com",
    "thedatabase",
    "username",
    "password",
  ),
  ...
});

However, when I set it up, I run into the following error:

Property 'Session' does not exist on type '{ SESSION_COOKIE_NAME: string; beginAuth(request: IncomingMessage, response: ServerResponse, shop: string, redirectPath: string, isOnline?: boolean | undefined): Promise<...>; ... 4 more ...; getCurrentSessionId(request: IncomingMessage, response: ServerResponse, isOnline?: boolean | undefined): string | undefined; }'.ts(2339)
}

My server crashes because: TypeError: Cannot read properties of undefined (reading 'PostgreSQLSessionStorage')

I've tried importing PostgreSQLSessionStorage directly for use like so:

import { PostgreSQLSessionStorage } from "@shopify/shopify-api/dist/auth/session/index.js";

But that runs into a whole host of other undefined object issues.

Any idea where I'm going wrong?

Did you ever get this worked out? Removing Auth got me a little closer:

SESSION_STORAGE: new Shopify.Session.PostgreSQLSessionStorage(`${process.env.DATABASE_URL}?sslmode=require`),

But now i get

Inquisitive Tom solution worked for me as well. To wrap it up, in order to switch to heroku postgresql from sqlite (original shopify CLI db), you have to:

• Deploy on heroku
• Create a db
• Add "PGSSLMODE: no-verify" in Heroku Config Var
• Get your database credentials in Heroku
• Replace below line of code in Shopify.Context.initialize inside index.js (be careful to replace all variables: username, password, host, database). Don't include "auth" as opposed to what is shown in Shopify Doc.

SESSION_STORAGE: new Shopify.Session.PostgreSQLSessionStorage("postgres://username:password@host/database")
