Hi Experts,
a few days ago, I found an article on the Office | Dev Center. The article's name is <Use the SharePoint JavaScript APIs to work with SharePoint data>. I followed all steps of the article but is not working. And I got a error message when I wanted to test it after published it. As follows. The correct SharePoint platform is SharePoint online not on premise.
How should I handle it to solve my issue.
Thanks a lot
