For the last several days the vector store objects I’ve created disappear, files uploaded disappear, but they seem to remain attached to their respective assistants until that disappears too. Is anyone else having the same problem or know what is going on?

I’m sorry to hear that, can you give me a bit more detail to help debug the issue. What is your organization id and which endpoints are things disappearing from?

Our organization ID is: org-fpnAeX6JRglMqW5PY9gETKhK Thank you so much for jumping in to help. This is a very strange issue that has never happened before. Currently I am creating vector stores and supplying them with files using the API Platform. I also use the API Platform to create the assistan…

I posted here a message because I’m experiencing something similar . In my case what I think is playing an important role in making vector stores disappear, is the use of project keys. If I create a store via the web UI, the store gets created and it is visible both in the UI and also if I list t…

Yes there is currently a huge bug going on, and it should be classified as a CRITICAL OUTAGE!

The team has identified the issue, has a plan to fix it, and will be fixing it as soon as possible. Your vector stores are still in the system and usable, it is just the list vector stores endpoint that is impacted. We are planning to ensure all of your vectors stores show up in the list endpoint on…

Project Scoping? Perhaps you can detail if there will be any aspect of user data scoping to within projects now or in the future. This was hinted a bit early on, and there’s also a file upload purpose “user-data” that works similarly to “assistants”, but server-side client data such as threads, file…

Do you have a timetable that you can share with the community?

Apologies for the delay, this one was very tricky to resolve. We believe the issue is resolved for all new vector stores and are working on backfilling all data that was not appearing. I don’t have an ETA on the backfill (we aren’t far enough along in the process to have a good guess at this point),…

No apologies needed. I’m glad we could discover this for you. The timeframe for the backfill is completely reasonable and the fact that new vector stores are now working is great! Thank you very much.
