Issue with ClickUp API Pagination in Qlik (Rest Connector)

I'm working with ClickUp's API using the REST connector and facing an issue with pagination. The ClickUp API provides only a page query parameter for pagination, and the response includes a last_page boolean in the JSON. However, I couldn't use the pagination feature provided in the Qlik REST connector since it only supports next_page and last_page, and I only have access to the page parameter.

To handle pagination manually, I implemented a DO WHILE loop in the script. Despite this, I still face redundancy issues with many tasks having the same key_task, resulting in duplicates + im not really getting all the tasks from the 9 pages some are still missing. Here’s a snippet of my code:

LET page = 1; // Start with page 1

//***************************************************************************************
LIB CONNECT TO 'Dev_Tasks';

// Loop to fetch all pages
DO WHILE page <= 9
// Chargement des données depuis le connecteur REST
RestConnectorMasterTable:

(SELECT
"id" AS "id_u9",
"custom_id",

WITH CONNECTION (

);

// Increment the page number
LET page = $(page) + 1;

// Trace the current page number for debugging
TRACE Page Number: $(page);

LOOP;
