Unhandled rejection TypeError: Cannot read property 'key' of undefined.

See original GitHub issue

I have a migration set up that worked previously. When I go to run sequelize db:migrate. I get the following error output.

This bit me too. I was wanting to change a column to allow NULL values. I was using the following code:

    queryInterface.changeColumn(
      'myTable',
      'someColumn',
      {
        allowNull: true
      }
    );

… but things did not start working until I specified a type:

    queryInterface.changeColumn(
      'myTable',
      'someColumn',
      {
        type: Sequelize.STRING,
        allowNull: true
      }
    );

Figured it out. I wasn’t specifying a type for an array.
