Instantiating a combo box with no language throws error

On v4.0.12, when trying to instantiate a combo box using

$(’#selectID’).select2();

it throws an error in the output that says

Exception was thrown at line 225, column 13 in https://localhost:44318/ProjectName/lib/select2/js/select2.full.js
0x800a139e - JavaScript runtime error: No en

It successfully creates the combo box, but still throws the error. I think that the bug could be being produced from select2.full.js line 4976

// Always fall back to English since it will always be complete
options.language.push(‘en’);

and it should instead be

// Always fall back to English since it will always be complete
options.language.push(‘select2/i18n/en’);

Is this a bug or am I doing something wrong.
