Issue updating foreign key (typo in migration key?)

I ran into an issue with wanted to update the foreign key on a record. When I try to do this I get an error. Based on the error i’m not sure if the original schema key is incorrectly named (note I used interest_list singular in the ecto part) or if it’s another problem. Also notice how the two tables are combined in the foreign key (may be normal though not sure).

What i’m trying to do it take an "Interests" record and change the id to a different existing "interest_lists" record.

I also wasn’t sure if updating a foreign key is disallowed. I’ve tried to update the key in the Postgres GUI and that works fine.

     * foreign_key: interests_interest_list_id_fkey

 If you would like to convert this constraint into an error, please
 call foreign_key_constraint/3 in your changeset and define the proper
 constraint name. The changeset has not defined any constraint.

I have an `interest_lists` table that has many `interests` (one to many). However when I made the migration I mistyped the key... should have been `interest_lists_id` (lists with an s) I think?

current code:
