This is related to ESLint doesn't support spread operator in objects #10307, where full description of various alternatives on how to fix it is listed.

Essentially it boils down to changing to ecmaVersion: 2018 (or the equivalent ecmaVersion: 9), which is when it first was officially supported. With this change there is also no need for the experimentalObjectRestSpread: true any more.
