Hello, I am new to supabase. I am trying to create foreign keys but i am not able to. If i create a foreign key from the "Edit Table" option, it says that it is successfully created but it doesn't show in the table. When i try to create it using the "Add Column" option, it gives me an error "Invalid Input Syntax for Bigint:". I tried changing the datatype of the primary keys of all my tables to int2, still the same issue. Can somene help me resolve this.
