Check the spelling, and also make it nullable and add empty string or 0 value every variable and when you query make it list

@Ume Channel that didn't help i did give default values for everything still it didnt help

[Bharat Kumar]

The thing that helped me is i did make the id a string and while inserting i assigned the object id as hex String
