Hi @miguelgrinberg, thanks for creating slam!
I wanted to try this out so I followed the instructions of the first tutorial (fizzbuzz). I'm getting an error which is possibly related to the fact that I'm using a child aws account which does not have permissions to certain actions. I did not try with the root account yet, but I thought it would be nice to have a --verbose option to see what happened.
Here is the error log

The error suggests the S3 bucket that you requested does not exist.

I think this happens because one cannot use capital letters in S3 bucket names. According to the AWS-docs: https://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html

Bucket names can consist only of lowercase letters, numbers, dots (.), and hyphens (-).

In the code (init(), line 119), it says:

random.choice(string.ascii_uppercase + string.digits)

changing this to:

random.choice(string.ascii_lowercase + string.digits)

makes the bucket creation operation succeed.
