The directory exists in a subdirectory that is mounted
The user running Bitbucket doesn't have proper permissions
Security hardening (such as via AppArmor) is enabled
Solution
Ensure the mounted directory has "exec" permissions
The BITBUCKET_HOME directory (and all subdirectories) are owned by the user running Bitbucket and have read, write, and execute permissions.
Disable security hardening (or re-configure it in such a way it doesn't affect Bitbucket Server)
