Why doesn't the error message state what entity that causes the error?

I see this in my logs.

So probably I have deleted a helper or something that was used in the template of another entity, or the template is still there of that entity.
I can’t see anything that looks suspicious in my customize.yaml.

But why does not the error message include more “helpful” details?

Duplicate. Though admittedly the title of the previous post could have been clearer:
