Error with Views for ai_search: The "" entity type does not exist.

Switching to the correct tag

I will take over of this issue

Thanks to report this issue @damienmckenna

I've been testing it with next configuration:

Drupal 11.2.2
AI Core 1.1.x
AI Search 1.1.x
AI Assistant Api 1.1.x
AI Agents 1.1.x
Huggingface Provider 1.0.x
Sqlite Provider 1.0.x
Search API 1.38

From Huggingface provider I have used the next models:
Chat -> Meta Llama-3-8B
Embeddings -> MxBai Embed Large v1

And I have needed to apply the next patch in Search API in order to can create the view:
https://www.drupal.org/project/search_api/issues/3531256 🐛 Cannot create Search API based views On Drupal 11 Active

I was NOT able to reproduce the error that you are describing. Maybe the problem could be the fields that you are using in Search API Index, and the filter criteria added to the view.

I am using the next fields in Search API Index:
- rendered_item with type fulltext and main content as indexing option
- url with type string and Contextual content as indexing option
- title with type fulltext and contextual content as indexing option

Then in the view I am adding Fulltext search as filter criteria, then when I perform a search query everything works as expected.

Moving this issue to Postponed until we get more info about the issue in your side.

I suspect this is an upstream issue as I have seen this error in the past and required cache clearing to sort. Some possibilities:

• 🐛 SQLSTATE[40001]: Serialization failure: 1213 Deadlock found Postponed: needs info
• 🐛 Consider to remove exception handling from search_api_views_data Needs review

Feel free to re-open if we can have steps to reproduce that related to AI Search. Thanks!
