eWallet Integration Issue #90
Description
Hello! I encountered a problem when implementing eWallet payments using xendit-python==7.0.0.
My Code
import uuid
from xendit import ApiClient, Configuration
from xendit.payment_request import PaymentRequestApi
api_client = ApiClient(configuration=Configuration(
api_key="my_key"
))
api_instance = PaymentRequestApi(api_client)
payment_request_parameters = {
"reference_id": str("my_id"),
"amount": 50000.0,
"currency": "IDR",
"metadata": {"example": "example"},
"description": "test payment",
"payment_method": {
"type": "EWALLET",
"reusability": "ONE_TIME_USE",
"ewallet": {
"channel_code": "SHOPEEPAY",
"channel_properties": {
"success_return_url": "https://o-la-la.com/success",
"failure_return_url": "https://o-la-la.com/success",
}
}
}
}
response = api_instance.create_payment_request(
idempotency_key=uuid.uuid4().hex,
payment_request_parameters=payment_request_parameters
)Error Message
I got the following exception in module xendit.model_utils line 1452:
xendit.exceptions.ApiTypeError: Invalid type for variable 'url_type'. Required value type is str and passed type was NoneType at ['received_data']['actions'][1]['url_type']
API Response
When I examined the raw response, it was:

}Root Cause
The issue appears to be in the xendit.payment_request.model.payment_request_action.PaymentRequestAction class. According to the openapi_types function, url_type is defined without allowing null values, but the API response contains null for this field in the second action item.
class PaymentRequestAction(blabla):
...
@cached_property
def openapi_types():
"""
This must be a method because a model may have properties that are
of type self, this must run after the class is loaded
Returns
openapi_types (dict): The key is attribute name
and the value is attribute type.
"""
return {
'action': (str,), # noqa: E501
'url_type': (str,), # noqa: E501
'method': (str, none_type,), # noqa: E501
'url': (str, none_type,), # noqa: E501
'qr_code': (str, none_type,), # noqa: E501
