CORS Errors with LocalHost

I've been testing an application and up until yesterday everything was working fine. Now, I'm getting CORS errors on localhost. I didn't think this was possible as its still the same domain. For context, i'm runnning a next.js frontend which is calling a FASTAPI backend. For testing, my FASTAPI CORS config looks like this:

app = FastAPI()


app.add_middleware(
    CORSMiddleware,
    allow_origins=[
        # "https://mergersai.io",
        # "https://www.mergersai.io",
        "*",
    ],  
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
    expose_headers=["*"],
)

Error: Access to XMLHttpRequest at 'http://localhost:8000/start_scraping' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Has ayone got any ideas? I'm at a loss at how to troubleshoot.
