🐛 Describe the bug

I followed directions here: #8495
to run a small vision test.

vllm serve microsoft/Phi-3.5-vision-instruct --trust-remote-code --max-model-len 4096
Benchmark with image of chart2text(cauldron) subset from [lmms-lab/LLaVA-OneVision-Data](https://huggingface.co/datasets/lmms-lab/LLaVA-OneVision-Data)

python benchmarks/benchmark_serving.py --backend openai-chat --base-url http://0.0.0.0:8000/v1 --endpoint /chat/completions --model microsoft/Phi-3.5-vision-instruct --dataset-path lmms-lab/LLaVA-OneVision-Data --dataset-name hf --hf-subset "chart2text(cauldron)" --hf-split train --num_prompts=10

I get this error:

INFO:     127.0.0.1:49806 - "POST /chat/completions HTTP/1.1" 404 Not Found

Did this used to work? Thanks!
