Hi, I have checked meta api, and yes I have found a bug (It will be fixed in next release), but not with your exception, maybe it will fix even this.
Meanwhile you should check your model, because this kind of error may appear if automap_base of sqalchemy is not able to create model objects as AutoCrud expects because of missing constraints, for example: every table must have a primary key, every related tables must have a foreign key and other things like these...

Fixed with release 2.2.1
