Why did a log line cost money? Does GCP charge for logging?
it's in the issue. I'm not sure why you would run anything in the cloud without some sort of kill switch or major alerting. You are potentially risking bankruptcy unless you are able to get enough social media attention for them cloud provider to waive your bill.
The cloud providers should be forced to add a "kill my services at this cost point" feature
You could argue that there should be some sane defaults though.
GCP, AWS, etc are usually good about waving bills if it's very clearly an accident and the first time it happened, especially if you catch it early. Not always of course, but it's a good idea to create a billing support ticket if this happens.

I can't recommend any service with open-ended pricing to any student or beginner. They risk bankruptcy.
