[Python] Gemini API Python {'result': 'error', 'reason': 'InvalidSignature', 'message':...

I Am getting an error when using the [Gemini API documentation][1] while following the documentation for a Private API invocation.

The json output is:

{'result': 'error', 'reason': 'InvalidSignature', 'message': 'InvalidSignature'}.


My code:

gemini_api_key = getMasterApi()#gets master api key from a json file
gemini_api_secret = getSecretApi().encode()#gets secret api key from a json file
print(gemini_api_secret)
t = datetime.datetime.now()
payload_nonce = str(int(time.mktime(t.timetuple())*1000))
payload = {"request": "/v1/mytrades", "nonce": payload_nonce}
encoded_payload = json.dumps(payload).encode()
b64 = base64.b64encode(encoded_payload)
signature = hmac.new(gemini_api_secret, b64, hashlib.sha384).hexdigest()

request_headers = {
'Content-Type': "text/plain",
'Content-Length': "0",
'X-GEMINI-APIKEY': gemini_api_key,
'X-GEMINI-PAYLOAD': b64,
'X-GEMINI-SIGNATURE': signature,
'Cache-Control': "no-cache"
}

response = requests.post(url, headers=request_headers)

my_trades = response.json()
print(my_trades)
