Cannot migrate database schema error: The associated field "todoListId" in the foreign key constraint does not exist"

Describe the bug

What is the problem

When I was doing code practice in the Running on relational databases section, running npm run migrate reported an error:
Cannot migrate database schema error: The associated field "todoListId" in the foreign key constraint does not exist,

The connected DB

Consistent with tutorial - Postgre DB

How I handle it

Change the value of the foreignKey to full lowercase
todo.model.ts

@model({
  settings: {
    postgresql: {
      schema: 'lb4', // schema name
      table: 'todo'  // table name
    },
    foreignKeys: {
      fk_todo_todoListId: {
        name: 'fk_todo_todoListId',
        entity: 'TodoList',
        entityKey: 'id',
        foreignKey: 'todolistid', // The value in the official tutorial is todoListId
      },
    }
  }
})
export class Todo extends Entity { 
// etc
}

Suggestion

Whether the code content should be changed in the tutorial
Transform: foreignKey: 'todoListId' -> foreignKey: 'todolistid'
