error: Unexpected keyword argument "astext_type" for "JSONB"

[triptec]

I'm getting error: Unexpected keyword argument "astext_type" for "JSONB" in my alembic migrations on lines like:
sa.Column("data", postgresql.JSONB(astext_type=sa.Text()), nullable=True),

Looking at the init function of the JSON class that JSONB inherits it has a keyword argument astext_type.

Can't find the init function for JSON/JSONB in this repo.

So, am I doing something wrong or is there something not implemented or whatnot?

Thanks!
