Vector Store file ingestion failing consistently for .docx files (server_error)

API Bugs

1

Hi everyone,

I am encountering a persistent issue when trying to add .docx files to a Vector Store.

I have tested this via both the API and the OpenAI Platform UI (dashboard), and the result is the same: .docx files fail to process, while other formats like .pdf and .txt are ingested correctly in the same Vector Store.

Here are the details:

  • Issue: .docx files immediately go to status: "failed".

  • Comparison: As seen in my screenshots, files like farmacia.pdf and New Text Document.txt were successfully processed, but Doc1.docx and other Word documents failed.

  • Chunking Strategy: Static (Max 800, Overlap 400).

The API response returns a generic server_error:

{
“id”: “file-TBhdGkr5F7yrBxCSaJJPZ9”,
“object”: “vector_store.file”,
“status”: “failed”,
“created_at”: 1769128030,
“usage_bytes”: 0,
“vector_store_id”: “vs_6972bede3c0c8191aeabb12e79ea42c2”,
“last_error”: {
“code”: “server_error”,
“message”: “An internal error occurred.”
},
“attributes”: {},
“chunking_strategy”: {
“type”: “static”,
“static”: {
“max_chunk_size_tokens”: 800,
“chunk_overlap_tokens”: 400
}
}
}

Has anyone else experienced issues with the .docx parser specifically? Is there a known outage or a specific requirement for Word files that I might be missing?

Thanks in advance for your help.

I am also facing issues with vector store file creation this week even for simple txt files (100KB).
