There was no button below the instructions to let me report something wrong, so I'm mentioning it here.
I just had the same problem as described in this post, the console passed me after I gave an incomplete answer : https://discuss.codecademy.com/t/introduction-to-objects-i-validation-error/42092?u=greggv
I think that the codecademy console needs to be more reliable in spotting errors. Passing people through with incorrect or incomplete answers may sound like a bonus to some, but it doesn't do a student any lasting favours and ultimately erodes confidence in codecademy as a learning platform.
I hope that the console is getting a good seeing to now that the Pro option has rolled out.
