🐛 If this PR is related to an issue, please put the link to the issue here.

The following issues are related, because "Install individual components" is not correct.

• After install as "Install individual components", I can not connect to the central dashboard.
• And this is related closed issue [backend] Cannot get MLMD objects from Metadata store. Cannot find context (Version 1.9.0-rc.2) #2800, the message "Cannot get MLMD objects from Metadata store." appeared when I install with "Install individual components" method.
• This update has to be applied to v1.9.0 also, so I will make a PR for v1.9.0
