Integrating Notion as a headless CMS in Next.js, I observed that column_list blocks yield empty child content. Try this revised method for retrieving nested blocks:
async function fetchChildBlocks(parentId) {
let blocks = [];
let pointer = null;
while (true) {
const response = await notionAPI.getChildren({ id: parentId, cursor: pointer });
blocks = blocks.concat(response.items);
if (!response.cursor) break;
pointer = response.cursor;
}
return blocks;
}
After working with Notion’s API in a Next.js setup, I experienced a similar issue where column_list blocks weren’t showing child content. In my case, I discovered that the issue sometimes stemmed from the asynchronous nature of the API calls. I solved it by ensuring that each fetch was completely finished before moving on, and carefully handling pagination. Paying attention to the API’s cursor mechanism and validating that all items got appended to my data structure proved to be the key in obtaining complete and consistent results.
During my integration of Notion’s API with Next.js, I encountered similar issues with retrieving child content in column_list blocks. I realized that the root cause was not only related to API pagination but also due to subtle race conditions in the asynchronous calls. To address this, I enhanced the implementation by ensuring proper synchronization for each page of results and added thorough error verification. This adjustment not only stabilized the data retrieval but also ensured all nested content was available. Examining the API’s behavior and response structure helped me refine the solution for a more reliable integration.
i had this issue too, and i noticed adding a slight delay in the while loop helped sync the async fetches, ensuring no child content was skipped. hope this remedy works for you!
