tg-admin create fails with SQLAlchemy ('ForeignKey' object has no attribute 'dialect_impl')

[Outworlder]

When issuing the tg-admin create, I get the following traceback:

$ tg-admin sql create
...detected

Found out what the problem was.

Instead of

Column('name', Integer, ForeignKey?('table.column'))

I wrote

Column('name', ForeignKey?('table.column'))

without the type.
