TypeError: (intermediate value).data.map is not a function

[taskani1010]

Hi, I am getting the following error, regardless of running locally or in a docker container:

> 116117bot@0.1.0 start
> ts-node index.ts
Booting 116117bot
TypeError: (intermediate value).data.map is not a function
  at Impfbot.findAppointmentsInUrl (/Users/user/Documents/CodingProjects/116117bot/index.ts:93:10)
  at processTicksAndRejections (node:internal/process/task_queues:94:5)
  at Impfbot.runLoopStep (/Users/user/Documents/CodingProjects/116117bot/index.ts:59:11)
Error 1, delaying next request.

Any help is greatly appreciated!

Changing the URL in line 90 in index.ts from https://001-iz.impfterminservice.de/assets/static/its/vaccination-list.json to https://002-iz.impfterminservice.de/assets/static/its/vaccination-list.json fixed the issue for me.

Hi @scho,

thanks for the fix. Unfortunately I still get the following error:

There have been significant changes to impfterminservice.de yesterday, which basically render this bot useless for now.

Among other things, they introduced an IP-based rate limit and now require sessions cookies to be set prior to checking type-1 availability. Details e.g. at https://www.stuttgarter-zeitung.de/inhalt.corona-impftermine-impftermin-website-blockiert-automatische-abfragen.7fa61c39-3e65-4d85-9bef-61babe8a0cb7.html.

Hi @joshuajung,

sad to hear. Thanks for your efforts! Would be awesome if this coud be circumvented in some way, I am sure we will have to deal with lack of appointments for a long time still...

Cheers
