Right, with the endpoint in the initial API call I am specifying .json. The issue I was noting was that in the response, the load_more_directory_items under meta did not specify .json.
"meta": {
"last_updated_at": "2020-08-11T11:40:43.000Z",
"total_rows_directory_items": 1132,
"load_more_directory_items": "/directory_items?order=days_visited&page=2&period=all"
}
The value is: /directory_items?order=days_visited&page=2&period=all
When it should be: /directory_items.json?order=days_visited&page=2&period=all
Since it doesn’t include .json, I have to manually update that string each time I need to page.
