This answer partially references GPT and GPT_Pro to solve the problem better.
First, check whether the field actually exists in the database. If it does, go ahead and check. Second, you need to check whether the corresponding table Settings are incorrect, such as whether the field is checked to display, or whether the position of the field is set correctly(for example, at the front of the displayed list). Also, check whether it is possible that the front-end JS may have masked it, such as being set to hide, or deleted.
Finally, if nothing works, we can locate the problem by adding a debug code to the server, for example, adding console.log() to the code to print out the field information we want to see, to help us find the problem.
// 添加 debug 代码 console.log('pen field: ', penField)
The above method can help you locate the problem and solve the problem that no field is displayed in the list.
