Start at ManageWebhooksApi.getWebhookSubscriptionsByOrg and the ApiClient.deserialize path shown in the stack trace. Compare the response shape expected by the webhook subscription call with the object returned by the API; done means the request no longer fails with Gson's BEGIN_ARRAY/BEGIN_OBJECT error.
