While running the insert without validation it works, but when I added validation like targetdate must be future date and trying to show in form twoway binding, then this error started.
No idea on which direction I need to think of.

Tried to debug the code and the error is triggered only when validation + two way binding are added. Without validation + two way binding tags, everything works fine.
PROBLEM is solved now by just adding @Valid @ModelAttribute("todooo")
Thanks to ...
The error comes to you application because you didn't specify an attribute of the model passed to the POST method. Add @ModelAttribute("todooo") to the method parameter:
public String post_insert_data(ModelMap modelMap, @Valid @ModelAttribute("todooo") Todo todooo, BindingResult bindingResult){
