As written in the tutorial, an error was reported when querying the data, and the output content was fine. Later, I found that I didn't notice that date was written as data in the template, and in the end it kept getting errors. No matter how I changed it, it was useless. It has been solved.
It has been solved. There is no problem with the query statement. The data in the view layer was written incorrectly. The date was written as data, but I didn’t notice it. I didn’t miss it usually, and I didn’t expect this.
