Answer 1

the error is related to the time line in the fail statement,

config.response.data({
                            error: true,
                            messages: 'Something went wrong.',
                            t: t
                        });

you might want initially hard-code t to a valid date just so that you remove any suspicion about this t variable and possible problem of casting, parsing.. Once it does work, you will be left with an issue that is about syntax, or parsing of the data
