500 - Internal Server Error calling py-sdk

Today, I was exploring the features of the Alpaca broker and delving into the Alpaca Py SDK and found an example of creating a new account. I’ve just changed a bit the original example and tried to send a request through BrokerClient() with active sandox=True, the server responds to me every time with 500 status code, original details are: “code”: 50010000 and “message”: “internal server error occurred”

These are the headers used in the request:

{‘Date’: ‘Tue, 17 Oct 2023 18:52:39 GMT’, ‘Content-Type’: ‘application/json; charset=UTF-8’, ‘Content-Length’: ‘60’, ‘Connection’: ‘keep-alive’, ‘Access-Control-Allow-Origin’: ‘*’, ‘Vary’: ‘Origin’, ‘X-Ratelimit-Limit’: ‘1000’, ‘X-Ratelimit-Remaining’: ‘999’, ‘X-Ratelimit-Reset’: ‘1697568759’, ‘X-Request-Id’: ‘82077de6730adb1ea6a847f65ce5f0e5’, ‘Strict-Transport-Security’: ‘max-age=31536000; includeSubDomains’, ‘Access-Control-Allow-Credentials’: ‘true’, ‘Access-Control-Allow-Methods’: ‘GET, OPTIONS, PUT, DELETE, POST, PATCH’, ‘Access-Control-Allow-Headers’: ‘Apca-Api-Key-Id, Apca-Api-Secret-Key, Authorization’, ‘Access-Control-Max-Age’: ‘1728000’}

Here is my code:

broker_client = BrokerClient(
api_key=ALPACA_TOKEN,
secret_key=ALPACA_SECRET_KEY,
sandbox=True
)

# Make a request to create a new brokerage account
