Cannot find an index in the referenced table where the
referenced columns appear as the first columns, or column types

Note that the internal storage type of ENUM and SET changed in
tables created with >= InnoDB-4.1.12, and such columns in old tables
cannot be referenced by such columns in new tables.
Please refer to https://mariadb.com/kb/en/library/foreign-keys/ for correct foreign key definition.
