Panic Output

Expected Behavior

Either the creation of the route table is successful and the route table has an ID. Or the creation of the route table is unsuccessful.

Actual Behavior

The creation of the route table is successful but the route table has no ID. This causes subsequent resources that depend upon the route table to fail.

Steps to Reproduce
