Bitbucket workspace invitations failing for all users

We have successfully mitigated the incident and the affected service is now fully operational. Our teams have verified that normal functionality has been restored. Thank you for your patience and understanding while we worked to resolve this issue.

Users of Bitbucket Cloud currently face difficulties when trying to invite new users to their workspaces. This issue is resulting in a '400 Client Error: Bad Request' message, which stems from a recent change in the invitation flow. The team is actively working on a resolution and is deploying a hotfix. We will provide an update within the next hour.
