This error occure when assigning the dialogData with the object which we got it from form.
this.dialogData = userObj;

if we put before post request in Service class it is working, But id and created_at and update_at are emty, In my case ID is auto increament and created_at and update_at are set to default value current date. So user wont supply it from the front end. Once the user object persisted in to the data base. These value id,created_at and update_dt are should assign to the front end list.

Please suggest how we can overcome this.

Thanks
Mohsin

You might want to check out this or other samples how to retrieve current date/time:

In my projects backend generates date and time.

[atmohsin]

dialogRef.afterClosed().subscribe(result => {
if (result === 1) {
// After dialog is closed we're doing frontend updates
// For add we're just pushing a new row inside DataService
setTimeout(() => {
this.exampleDatabase.dataChange.value.push(this.dataService.getDialogData());
this.refreshTable();
},2000);
}
});

I made some delay, so that the object get from API set it.

Use below code it's working!!!

setTimeout(() => {
this.exampleDatabase.dataChange.value.push(this.dataService.getDialogData());
this.exampleDatabase.getAllIssues();
this.refreshTable();
}, 1500);
