I am using Brave but also tried in google chrome and I have the same error. I new in the plataform, and I have seen that this error is very common but they dont explain how to solve it.
I hope someone can help me.
The particular API returning where a vector store is used has broken before.
It also will no longer have a server-side destination to report about:
assistants with preconfigured vector store is shut off;
prompt presets for Responses with tool configuration will be shut off.
Thus the question “where is my vector store being used” can only be answered by you and the API calls you make with “tools”->“file_search”.
That UI and its endpoint call should be shut off by OpenAI. Even the placeholder for me having no vector stores, “Vector stores allow Assistants to search information” refers to a shut-off endpoint feature.
