CORS Error - Trigger OPTIONS

So my server is hosted with workers and my client is hosted on another domain so keep running into the same errors regarding CORS. Here's a code snippet of the function that's causing the error. If anyone has any advice let me know.

async def on_fetch(request, env):
    if request.method == "OPTIONS":
        # Handle preflight requests
        headers = Headers.new({
            "Access-Control-Allow-Origin": "*",  # Allow requests from any origin
            "Access-Control-Allow-Methods": "GET, POST, OPTIONS",  # Specify allowed methods
            "Access-Control-Allow-Headers": "Content-Type",  # Specify allowed headers
        })
        return Response.new(None, status=204, headers=headers)
    else:
        # Handle other requests
        payload = json.dumps({ "business": random.choice(business), "concept": random.choice(concepts) }, sort_keys=True)
        headers = Headers.new({
            "content-type": "application/json",
            "Access-Control-Allow-Origin": "*",  
        })
        return Response.new(payload, headers=headers)

async def on_fetch(request, env):
    if request.method == "OPTIONS":
        # Handle preflight requests
        headers = Headers.new({
            "Access-Control-Allow-Origin": "*",  # Allow requests from any origin
            "Access-Control-Allow-Methods": "GET, POST, OPTIONS",  # Specify allowed methods
            "Access-Control-Allow-Headers": "Content-Type",  # Specify allowed headers
        })
        return Response.new(None, status=204, headers=headers)
    else:
        # Handle other requests
        payload = json.dumps({ "business": random.choice(business), "concept": random.choice(concepts) }, sort_keys=True)
        headers = Headers.new({
            "content-type": "application/json",
            "Access-Control-Allow-Origin": "*",  
        })
        return Response.new(payload, headers=headers)

I have the error log issues if they are necessary.
