authentication example is broken/unusable

[seccentral]

Documentation Issue

Following the instructions at https://github.com/payloadcms/payload/blob/main/examples/auth/README.md should land you on localhost:3000 with a working login/dashboard/logout flow but multiple steps are broken.

Additional Details

npx provisioning works.
Starting the dev server does not, as it immediately crashes due to inexistent payload_secret and connect db string. (suggestion: a small declaration of a ./db.sqlite should be fine for this purpose)
Fixing that leads to an error due to graphql missing.
Adding that finally allows the server to start on :3000 and leads to a page that displays one nextjs error :

Runtime Error


Error: SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

src/app/(app)/_providers/Auth/rest.ts (32:11) @ rest


  30 |     }
  31 |   } catch (e: unknown) {
> 32 |     throw new Error(e as string)
     |           ^
  33 |   }
  34 | }
  35 |****

Ignoring that, the showcased login does not work with provided credentials (??) demo@payloadcms.com and password demo.
Logging in via admin panel, however, works and going back to /login shows You are already logged in., however, clicking the logout button does nothing visually and inspecting the console shows

rest.ts:11 
 POST http://localhost:3000/undefined/api/users/logout 404 (Not Found)
rest.ts:11 
 POST http://localhost:3000/undefined/api/users/logout 404 (Not Found)

A bit confusing for a newbie, right ?
