Forward engineering EER diagram in MySQL Workbench

Question

Using MySQL Workbench 5.2.33 with MySQL 5.1.41

I have created an EER diagram. But when I try to forward engineer it from MySQL Workbench, I get the following error:

Executing SQL script in server
ERROR: Error 1005: Can't create table 'test_db.test_table' (errno: 150)

ENGINE = InnoDB

Why am I getting this error?
