400 Error - Incorrect HTTP API Arguments

[tom42cap]

Hi,

I'm getting 400 - Incorrect HTTP API Arguments errors, saying that any required arguments are missing (for all the endpoints).

I'm making requests using Python 3 as follows:

def request(lua):
auth = HTTPBasicAuth(USERNAME, PASSWORD)

payload = { 'lua_source': lua }

res = requests.get(SPLASH_ENDPOINT, auth = auth, json = payload)

return res

And getting back (res.text):

'{"description": "Incorrect HTTP API arguments", "info": {"argument": "lua_source", "type": "argument_required", "description": "Required argument is missing: lua_source"}, "type": "BadOption", "error": 400}\n'

Where am I going wrong?
