For the past four days I’ve been getting the same error in the OpenAI platform whenever I open any of my vector stores: “An unexpected error occurred: Invalid URL (GET /v1/vector_stores/…)" The error appears for every vector store I own. The dashboard cannot load the vector store details or assoc…

Hi and welcome back! FYI: This has already been raised with the team when I saw other reports earlier today: [image] OpenAI Dashboard - Storage -> Vector Store Error API I reproduced this issue and flagged it to the team. Thanks for raising it here!

Also experiencing the same issue today

Hi OpenAI Developer Community, For several days, I had an issue when I create a vector-store. I upload some files using the File API I create a vector-store populated with the previously generated file identifiers I periodically check statuses of this vector-store and thefiles stay in_prog…

I’m also running into pretty bad performance when creating vector stores. Especially today, several have been hanging with just a few files in progress and never resolving.

Same here guys. I’ve tried associating files to a VS both via the WEB GUI and the API. Both have failed. When loading files from a VS by using the API, I can observe this within the response: “status”: “failed”, “last_error”: { “code”: “server_error”, “message”: “An internal error occurred.” } …

I’ve been getting a similar error. Uploading files is fine - but adding them to Vector Stores isn’t working (Indefinite hang). It seems like a VS issue, not a general or file issue.

Yeah we got the same problem but only when trying to attach pdf’s to the vector store. docx and txt seems to work fine.

This is actively being worked on. [image] OpenAI Dashboard - Storage -> Vector Store Error API We are working on fixing this issue. Apologies for the inconvenience.

Until now, Im facing the same problem

DO SOMETHING! It’s been a week already!!!
