What do you want to call your bucket? (default zappa-2o2zd8dg4)

Zappa deployments will need to be uploaded to a private Amazon S3 bucket. AWS Lambda requires two types of code entry, such as inline code and uploading the ZIP. If the ZIP file size exceeds 10 MB, then consider uploading the ZIP onto Amazon S3. This is why Zappa, by default, creates a bucket which will be used to upload the deployment ZIP file and refer to AWS Lambda.

You can provide your own existing bucket name or choose the default, as suggested by Zappa. If the bucket doesn't exist, then Zappa will automatically create one for you.
