Hey @serverlesspolska, thanks for submitting your issue.

This error happens when too many files need to be deleted on the s3 bucket holding your static website.

This is mostly due to previous delete operation from previous deployment silently failing.

This behavior has been fixed in https://github.com/getlift/lift/pull/115

Please ensure your deployment user has s3:deleteObject permissions, update to latest Lift version, delete all files in s3 bucket manually using the web console and try again.

Let me know if the problem still happens after that. Sorry for your trouble.
