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

SOLUTION

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

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

This is not solving for me I am getting same

An unexpected error occurred: Invalid URL (GET /v1/vector_stores/{id}/associations)
