[BUG] Indices page console errors and increased load times when new home page experience is enabled

[CaptainDredge]

What is the bug?
There seems some bug in indices page when experimental useNewHomePage feature flag is turned on. Any operation on indices page leads to a lot of warnings on console
This has also led to significant increase in child component rendering times. This is not an immediate problem but will lead to bad user experience

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Enable useNewHomePage feature flag
2. Go to indices page
3. Try to do any operation(create index, notification setting etc.)
4. See errors on console and feel the lag of loading components

What is your host/environment?

• OS: 2.15

Do you have any screenshots?
