Bug Report: cookieconsent.js:7 Uncaught TypeError: Cannot read properties of undefined (reading '0')

[ais8xl]

Hello,

Switching of cookie-param from accepted to rejected is impossible and returnes this error for the first click:

Uncaught TypeError: Cannot read properties of undefined (reading '0')
    at dn (cookieconsent.js:7:9354)
    at cookieconsent.js:7:15560
    at M.accept (cookieconsent.js:7:16226)
    at HTMLButtonElement.<anonymous> (cookieconsent.js:7:8525)

After the second click this error disappears and param is succcesfully switched-off, but after the page refresh this param is returned again (so cookies aren't off).

I use version v2.9.1.

My script:

const ccOptions = {
    auto_language: 'document',
    autoclear_cookies: true,

    languages: {
        'en': {
            consent_modal: {
                title: 'We use cookies!',
                description: 'The website uses cookies so that the website remembers whether you have already agreed to our use of cookies on this website. <button type="button" data-cc="c-settings" class="cc-link">Learn more</button>',
                primary_btn: {
                    text: 'Accept all',
                    role: 'accept_all'
                },
                secondary_btn: {
                    text: 'Reject all',
                    role: 'accept_necessary'
                }
            },
            settings_modal: {
                title: 'Cookie preferences',
                save_settings_btn: 'Save settings',
                accept_all_btn: 'Accept all',

                            }
                        ]
                    },
                    {

                    }
                ]
            }
        }
    },
};

var cc = initCookieConsent();

cc.run(ccOptions);

Thanks for answer in advance!

Hi @ais8xl,

you have enabled the autoclear_cookies option but you haven't configured the cookies to clear. Check out the docs on how to properly set this up.

Edit: cookie_table_headers must not be empty.
