The absolute paging query type that is being used has been deprecated. Starting Dec. 1, 2021 we will no longer return data for this query, and instead return a 400-response for requests of query type /Workers?Page=&PageSize=.
Please update your application to instead utilize relative paging: /Workers?PageToken=PA<task_sid>, where <task_sid> is the last item of the current page.
Not using the latest Twilio helper libraries. Constructing requests directly which use Page & PageSize query parameters directly.
Utilize the latest Twilio helper libraries. Rely upon the PageToken instead of the Page Number for paging.
