Entity Types Not Initialised: Speedrun AIP E2E Workflow

I’m trying to learn about the AIP workflows with the speedrun course. I am getting stuck at the stage where I need to create a vertex graph to connect my chunks to my entities. I have sen a similar discussion (linked below), but the given solution of ensuring all objects and links are indexed is not working for me. Any help in solving this issue would be greatly appreciated.

Hello rOcean!

Can you check if your many-to-many link has correctly indexed?
You can find it under the “Datasources” tab → “Object Storage V2” section.
