Failed to load resource: the server responded with a status of 500 (internal server error) — datatables forums

     
Because this table has a one-to-many relationship with another table, when table 1 is serialized, the field associated with another table 2 will be found, and it will be serialized in another table 2, and then in another table 2. There is also a field associated with Table 1. In this way, this kind of error occurs in serialization!【solution】

/Note: It is worth noting here that when there is a foreign key association, the serialization element must be specified. If there is no foreign key association, the entity object will be serialized directly return Json(new { ti.TypeName,ti.Typevalue,ti.UserId,ti.Remark,ti.FullPath,ti.TyId,ti.isdisplay}, JsonRequestBehavior.AllowGet);
