[Bug]: export_events fail because of invalid url

[vintersnow]

What happened?

I tried to call the export_events endpoint, and an error occurs.

Steps to reproduce?

import onesignal
from onesignal.api import default_api
from pprint import pprint

app_id = "" # The ID of the app that the notification belongs to. 
notification_id = "" # The ID of the notification to export events from. 
app_key = ""
configuration = onesignal.Configuration(
    app_key = app_key,
)

with onesignal.ApiClient(configuration) as api_client:
    # Create an instance of the API class
    api_instance = default_api.DefaultApi(api_client)

    # example passing only required values which don't have defaults set
    try:
        # Export CSV of Events
        api_response = api_instance.export_events(notification_id, app_id)
        pprint(api_response)
    except onesignal.ApiException as e:
        print("Exception when calling DefaultApi->export_events: %s\n" % e)

Then below error happen
