6 years ago Instead of trying to find out exactly what value it was attempting to use for the S3 Bucket Name, I instead tried using modified templates which shortened the value being used. From the issue @sysout reported, it may also be important to make sure that only lowercase letters are allowed, so I modified two of the templates to enforce that condition for the AppName value.
The modified templates I used are available here, but they would need to be updated to point to an S3 bucket of your own creation, before use: https://github.com/Pseudothink/aws-serverless-samfarm/tree/master/pipeline
After doing this, the CloudFormation stack seemed to get created properly (along with the S3 bucket), without error.
Very similar to the issue @sysout reported, I'm getting a similar error on Step 3. Just like @sysout, the repo I'm using is just the default files from the api subfolder, located in the repo root: https://github.com/Pseudothink/aws-serverless-samfarm
Here's the screenshot of my error (captured in the small interval of time between the CREATE_IN_PROGRESS status and the DELETE_COMPLETE status):
I'm going to see if I can find out what value it is trying to use for the S3 bucket name, but since these are the default files from the tutorial, I'm guessing that something on the AWS backend changed between the time the tutorial was published and now.
