To state my problem case:
My Auto Name spec is Foobar-.# that corresponds to this [series] - Series by prefix (separated by a dot)
When Foobar is a subclass of Document, autoname generates Foobar-1 as expected.
But when Foobar is a subclass of WebsiteGenerator I get this stack trace:
frappe@erpnext:~/frappe-bench$ bench run-tests --doctype Foobar --test test_create_Foobar
E
