... 6 moreCause
The root cause of this issue is that ElasticSearch and OpenSearch includes a validation step during startup that prevents it from running as the root user for security reasons.
Solution
To resolve this issue, ensure that Bitbucket is not run as the root user.
When starting Bitbucket manually, follow these steps:
Login as a dedicated Bitbucket user. The default is
atlbitbucket,but verify the correct user for your system.Start Bitbucket using this dedicated user account.
If running Bitbucket as a service:
