Error: .eslintrc.js:
        Configuration for rule "space-before-function-paren" is invalid:
        Value {"anonymous":"never","asyncArrow":"always","constructor":"never","method":"never","named":"never"} should be equal to one of the allowed values.
        Value {"anonymous":"never","asyncArrow":"always","constructor":"never","method":"never","named":"never"} should NOT have additional properties.
