🐛 Describe the bug

Simply run vllm serve facebook/opt-125m --enforce-eager and navigate to http://localhost:8000/docs

I can replicate this on the last several releases and using latest main:

Screenshot 2024-10-08 at 4 58 52 PM

The last release where the endpoint works properly is vllm==0.5.4. The following image is the expected result on page load.

Screenshot 2024-10-08 at 5 00 28 PM

In both cases, the server reports that the GET requests were successful:

talked to @mgoin on slack - I assigned this to myself and will track this down

I wasn't able to reproduce this.

Based on our discussion on slack, it sounds like it might be something on the browser side since the logs show successful requests on the vllm side.

INFO:     Uvicorn running on socket ('0.0.0.0', 9000) (Press CTRL+C to quit)
INFO:     127.0.0.1:35248 - "GET /docs HTTP/1.1" 200 OK
INFO:     127.0.0.1:35248 - "GET /openapi.json HTTP/1.1" 200 OK

maybe try a different browser? or turning off browser extensions that might be interfering?

I tried the latest version(0.6.3.dev148+gca77dd7a.d20241009) and it works in chrome and Edge browser.
