[Bug]: Example command to test domain proxy does not work

[kennedyjosh]

What happened?

Wanting to test my domain proxy, I copied this code from this webpage (replacing it with my own URL) and it doesn't work. I get back a 400 "Invalid JSON" error.

curl --data 'api_key=API_Key' --data-urlencode 'event=[{"user_id":"12345", "event_type":"test_proxy_event", "time":1396381378123}]' http://localhost:8080/amplitude/

The command on this page does work.

curl --location --request POST 'https://api.amplitude.com/2/httpapi' \
--header 'Content-Type: application/json' \
--data-raw '{
    "api_key": "YOUR_API_KEY",
    "events": [
        {
            "user_id": "12345",
            "event_type": "watch_tutorial",
            "user_properties": {
                "Cohort": "Test A"
            },
            "country": "United States",
            "ip": "127.0.0.1",
            "time": 1396381378123
        }
    ]
}'
