Hello 👋

I started use Discourse Ai - OpenAi API. First I seted up it to Related Topics (`text-embedding-ada-002`). When I try to run the [rake task for backfill](https://meta.discourse.org/t/discourse-ai-embeddings/259603/8). I’ve got the following error.

```plaintext
....rake aborted!
NoMethodError: undefined method `[]' for nil:NilClass (NoMethodError)
