Issue when trying to enroll after spot has freed up

[PaulPerpetual]

Firstly thanks for the bot, it's really useful! Today I have encountered an issue though when trying to log in to a lesson that was already fully booked and a spot freed up it gave me the following error messages. I assume that by the time that the script tried to enroll the spot was already taken?

Yeah, I recently also encountered this issue, and it may be indeed the case that it tries to enrol into a lesson that recently had free places but has none any more (someone else was faster).

As a workaround, I run the bot as follows, but I think this can also be integrated into the bot itself:

while ! python asvz_bot.py lesson <lessonId>; do done

I tried to address this issue with version 1.4.1. Let me know if this error still occurs.

[PaulPerpetual]

thanks!

sorry if this is off-topic but did you figure a way to run the code online? (so one does not have to have the own laptop turned on at the given time)

[fbuetler]

You can run the bot everywhere you have python3 and chrome/chromedriver installed. This is out of scope for this project, but you can check out for example https://fly.io or https://digitalocean.com.
