https://typescript-eslint.io/rules/no-unnecessary-template-expression/

This rule was called no-useless-template-literals in the past.
In terraform land it's the Interpolation-only expressions are deprecated warning.

Basically:

const MYSTR = "Hello";

const myComplicatedObject = {
  value: `${MYSTR}` // warning "no-useless-template-literals" -> change to value: MYSTR
}
