Vector store file uploads instantly failing with generic server_error since last night (docx, pdf)

Is anyone else seeing vector store uploads fail since last night? Files are instantly marked as failed with the same generic error:

"status": "failed",
"last_error": {
  "code": "server_error",
  "message": "An internal error occurred."
}

It looks file-type specific: Markdown and HTML uploads work fine, but every .docx and .pdf I try fails immediately, both through the dashboard and the API. Different file sizes, different documents, same result.

Nothing on the status page so far. Can anyone from OpenAI confirm if there’s an ongoing incident with the vector store processing pipeline for docx/pdf?
