EventBrite Changed Something

[isianonpaper]

Tried running ticket-info.js (10/20 update) and it errored out. Instructions were to let you know. 👍

Full code below with error message. Getting message on multiple pages (not isolated to one page). Had success as recent as two weeks ago.

ticket-info.js

}
}

var res = data.match(pattern);

return null;
}
var collectionText = '{' + res[0].replace("collection", '"collection"') + '}';
collectionText = collectionText.replace(/\t/g, '');

var result = null;

Can you give me a URL that was failing? Events whose Eventbrite pages look like this don't currently work:

[isianonpaper]

Hi,

So it doesn't currently have a drop down menu like the picture, but it is a multi ticket event.

https://www.eventbrite.com/e/barrel-aged-vietnamese-speedway-stout-mokasida-speedway-stout-bottle-release-tickets-28773797202?aff=es2

I forget the second URL I tried. I will look to add to this list when I get home and can try some others.

I did also try the old version from before the update a week ago--with a 1 instead of 10001--to no avail, fwiw.

EDIT:
After digging in further, it is working on older pages that I've run it on before--all single ticket events with the picture header at the top and the "details" button on the right side of the screen.

https://www.eventbrite.com/e/space-trace-bottle-release-tickets-28120857241
https://www.eventbrite.com/e/fundamental-observation-2016-bottle-release-tickets-25589624255#
https://www.eventbrite.com/e/leche-borracho-bottle-release-tickets-24635482391#

It's not working on the URL below. This page doesn't have the single header picture like the others, but seems to have an integrated design into the page. It's also missing the "Details" button, with "no ticket information" listed under the Ticket Info section. This makes me hesitant to believe they've uploaded the ticket info to Eventbrite. I may be searching for info that isn't out there yet.

https://www.eventbrite.com/e/barrel-aged-vietnamese-speedway-stout-mokasida-speedway-stout-bottle-release-tickets-28773797202?aff=es2

I'll continue to try periodically--especially once some info populates under Ticket Info--and let you know of the test results.

Edit #2:

I tried it on an old event from the same Seller (with the page format identical to the new sale) and it errored. This seems to be the known issue you've added to the README.

I would love to dig into this if someone could provide some links to events that the script doesnt work for.

@jmiazga havign trouble getting the info to work on this page https://www.eventbrite.co.uk/e/steelcon-2018-tickets-36060297320#tickets

getting error in firefox developer:

/*
Exception: TypeError: (new Date(...)).toLocaleFormat is not a function

EDIT: I believe Date.prototype.toLocaleFormat is deprecated
