Vector store file uploads instantly failing with generic server_error since last night (docx, pdf)
OpenAI Developer Community
May 9, 2026
Welcome to the forum!
I could reproduce this on my side.
Uploading the PDF to Files worked, but when I attached the same PDF to a vector store, it failed during the vector store processing step.
For comparison, a .yaml.txt file attached to the same vector store successfully.
So from my quick test, this does seem specific to certain file types during vector store processing, not normal file upload itself.
I also checked the status page and don’t currently see an incident listed for this:

Might be worth reporting to Support with failed file IDs, vector store IDs, timestamp, file types tested, screenshots and whether it happens through dashboard/API/both.
