My Strategy Dashboard say it missing "Error loading the section strategy: > [object Object]"

When i adding prediction entities to an entire section, like a :
slight_smile: strategy:
type: common-controls
title: Common controls

AND

In Strategy Dashboard, get this tip:
Error loading the section strategy:

[object Object]

how do i fix it?

You are not getting a single value back, but instead a collection of values and HA have no idea how to show that.

Check your core logs for errors related to usage_prediction. There have been some issues reported, that will manifest in that being printed.

But i don’t know how to fix it.

I don’t understand Use your words!

You don’t fix it, you post a bug report in the core repo (or check if it has already been reported), and one of the developers will fix it.

How do you “post a bug report in the core repo”
