Some ATS integrations work on some tenants but return empty responses on others for candidates

[io-ma]

Hello, thank you for offering this python wrapper , it is very useful.
We are trying to pull candidates from Breezy HR. The problem is the response we get is an empty list although we know for sure that there are candidates in that Breezy HR account.
We noticed a similar problem on Lever: on some tenants it works, but on others it returns an empty list.
Attaching a screenshot with the printed response:

Here's the call I make (this works just fine for other ATS integrations):

 with MergeATSClient.ApiClient(configuration) as api_client:

            api_instance = candidates_api.CandidatesApi(api_client)
            ats_integration = Integration.objects.filter(type='ATS').first()
            x_account_token = ats_integration.account_token

            try:
                api_response = api_instance.candidates_list(x_account_token=x_account_token, page_size=page_size, first_name=first_name, last_name=last_name)
                print('merge response', api_response)
