bug/coroutine-await

Describe the bug
i'm currently using the open source version of unstructured, and getting an exception about coroutine is being awaited already. This causes the parse to fail, and not work.

To Reproduce
It just seems to happen every so often, I'm not sure how to reproduce it. It's not on the same files, if I retry them, they'll succeed. I am putting a lot of files + data through the system, but nothing that seems to be something it shouldnt be able to handle.

Expected behavior
Not get this error.

Screenshots
N/A

Environment Info
I'm pullling downloads.unstructured.io/unstructured-io/unstructured-api:latest as my container and just running this.
Also running unstructured-client = "^0.23.8" on my client side.

Additional context
There's also a few warning that are showing up related to coroutines too:

Commencez par unstructured_client/_hooks/custom/split_pdf_hook.py vers la ligne 202 et examinez comment les coroutines call_api_partial sont stockées et attendues. Reproduisez l’échec intermittent avec la charge de travail à haut volume signalée, puis vérifiez que l’analyse se termine sans les avertissements « coroutine is being awaited already » ou « was never awaited ».
