We have implemented a fix in v2024.1.6809 which will be rolling out to cloud customers over the next two days. If you need the fix in your cloud instance sooner, please contact https://octopus.com/support. We will continue to monitor for any further issues.
We're investigating AWS deployment failures for customers upgraded to 2024.1.6245 and are using the "AWS service role for an EC2 instance" option, which throw the error "An account identifier was not found".
