Persistent “Invalid URL (GET /v1/vector_stores/…)” error across all vector stores — UI broken, cannot upload new files

[Sorin_Acela]

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 associations.
• Because of this, I cannot upload new files to any vector store.
• The assistant itself still works and can read from the existing vector stores, so the backend seems functional — the issue appears to be in the UI layer.

Reproduction steps

• Open any existing vector store in the dashboard
• The page immediately shows the error: “Invalid URL (GET /v1/vector_stores/…)"
• The interface fails to load the file list or associations
• The “Add files” button becomes unusable because the UI never finishes loading

Expected behavior

• The vector store page should load normally
• I should be able to upload new files to the knowledge base
• The UI should correctly call the vector store endpoints

Actual behavior

• The UI calls a route that appears to be invalid or deprecated
• The page fails to load
• Uploading new files is impossible
• The issue persists across all vector stores, not just one

Impact
This effectively blocks me from updating or expanding my assistants’ knowledge bases. The assistants can still query existing data, but I cannot manage or add new files.

Additional notes - The issue has been ongoing for 4 days - It happens in multiple browsers - No API key or permission errors - The assistant’s retrieval still works, so the backend vector store system is intact — only the dashboard UI is failing

Could someone from the OpenAI team confirm whether this is a known regression in the vector store UI and whether a fix is in progress? The topic was deal with before, but the error is fresh.

Hi and welcome back!

FYI: This has already been raised with the team when I saw other reports earlier today:

OpenAI Dashboard - Storage -> Vector Store Error

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_progress indefinitely

I have found a similar issue in this closed thread : Vector Stores not processing, staying in progress

Is there somebody with the same issue or an opened thread about this problem ? I really need to use a vector-store because I upload big files (> 50Mb) and pass them directly as attachment to Response API is not possible.

Thanks

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.

OpenAI Dashboard - Storage -> Vector Store Error

We are working on fixing this issue. Apologies for the inconvenience.

[Henrique_Corraro]

Until now, Im facing the same problem

[Sorin_Acela]

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

[Sorin_Acela]

No, nobody’s working. It’s been a week.

[urbassist]

Hi,
Attach pdf files to a vector-store works for me now : files are not infinitely “in_progress” anymore, but it is a quite long.
Thanks to all

SOLUTION (only has worked temporarily!)

After waiting in vain for an official solution, after trying various tricks, I solved it thus:

1. (in Chrome) Press F12 (DevTools will open).
2. Right‑click the Reload button.
3. Choose Empty Cache and Hard Reload.
4. Close DevTools.

This clears cached files and forces a full reload.

The https://platform.openai.com/storage/vector_stores/vs_6856………. page becomes functional again with no error.

The Vector Store bug discussed here seems to have not been resolved yet. I’ve been experiencing the same issue since this morning. Clearing the cache doesn’t fix it.

This is not solving for me I am getting same

Previously in this thread I provided a solution that only worked temporarily. The error reappeared and nobody seems to work on repairing.

Hi,

I can only partially reproduce this. I also see the error message An unexpected error occurred: Invalid URL (GET /v1/vector_stores/vs_6...8/associations). At first, I was unable to attach files to the vector store. After a short wait and a browser refresh, the file appeared and I was able to attach it to an assistant.

In the end, everything worked as expected, aside from the confusing error message. I verified this via the API as well and did not encounter any unexpected behavior there.

It is not a “confusing error message”. It is that this backend endpoint has again stopped working, just like in the past that took over a week to be addressed:

This is an endpoint that is supposed to return assistant IDs (or possibly prompts) where a vector store is attached to the file search tool. It is malfunctioning. Again. It is just more evidence that this company has too much technical debt and too little caring to do anything correctly or learn from mistakes, or that there is a new set of API developers that have not also learned from OpenAIs continued outages and ongoing API issues with malfunctioning products not working.

@_j

It seems that OpenAI dropped their API backend endpoint that shows the vector store “connections” in their vector store user interface (or it is just another thing malfunctioning for days…), but the Vector Store UI in the site still tries to make calls that would otherwise list the assistant IDs where a vector store is used. Something not on the API.

There should not be any API calls that you have to make - or can make - to that ../associations endpoint yourself in order to use Assistants with the file search tool. It is solely for OpenAI’s site, and as purely a part of the dashboard backend. Calls to that API URL are blocked without an owner session key by web browser (or a very good impersonation).

Any updates on this please? I get the same message for all my vector stores. And while it says that it has uploaded all the documents - when I scroll through them so many are missing. I have 98 txt files but the assistant is very clearly only using some of them. And despite the vector store sauing that it uploaded all the files I dont see them in the store. Super confused! (It’s my first time setting up an assistant on OpenAI). Not sure if there is somthing else going on or it’s this error (I would assume so - I’m just puzzled by the apparent upload/attachment seemingly uploading but then not appearing in the vector store)
