[Python] Kucoin Universal SDK : Invalid status code 400

I am new to algo trading and trying to get account information using the Kucoin account Api. When I run the code I am getting following issue:

/myenv/lib/python3.11/site-packages/kucoin_universal_sdk/internal/infra/default_transport.py", line 184, in process_response
raise RestError(None, f"Invalid status code: {resp.status_code}, msg: {resp_body.decode('utf-8')}")
kucoin_universal_sdk.model.common.RestError: request error, context msg: Invalid status code: 400, msg: {"code":"400001","msg":"Please check the header of your request for KC-API-KEY, KC-API-SIGN, KC-API-TIMESTAMP, KC-API-PASSPHRASE"}


My code is as follows:

k_api_key = os.getenv('KUCOIN_API_KEY')
k_api_secret = os.getenv('KUCOIN_SECRET_KEY')
k_api_passphrase = os.getenv('PASS_PHRASE')

# Initialize KuCoin client
# Set specific options, others will fall back to default values
http_transport_option = (
TransportOptionBuilder()
.set_keep_alive(True)
.set_max_pool_size(10)
.set_max_connection_per_pool(10)
.build()
)

# Create a client using the specified options
client_option = (
ClientOptionBuilder()
.set_key(k_api_key)
.set_secret(k_api_secret)
.set_passphrase(k_api_passphrase)
.set_spot_endpoint(GLOBAL_API_ENDPOINT)
.set_transport_option(http_transport_option)
.build()
)
client = DefaultClient(client_option)

account_api = client.rest_service().get_account_service().get_account_api()

getacctinfo = account_api.get_account_info()

print(getacctinfo.to_dict().values())


Any guidance to resolve this issue will be very helpful.

I tried setting up the api key, secret and pass phrase but no change.
