When i try to access object from developer console i get an error like below picture.
Also, when i use query editor and update some value on console, i get an error like below picture.
One more, when i try to update this object records from anonymous window, the log seems successful but the record isn't updated.
I don't get these errors except this object. I think there is something wrong with this object but i couldn't find what it is.
Help me!
