  Types of property 'a' are incompatible.
    Type '{ b: { c: { d: { e: { f(): { g: number; }; }; }; }; }; }' is not assignable to type '{ b: { c: { d: { e: { f(): { g: string; }; }; }; }; }; }'.
      Types of property 'b' are incompatible.
        Type '{ c: { d: { e: { f(): { g: number; }; }; }; }; }' is not assignable to type '{ c: { d: { e: { f(): { g: string; }; }; }; }; }'.
          Types of property 'c' are incompatible.
            Type '{ d: { e: { f(): { g: number; }; }; }; }' is not assignable to type '{ d: { e: { f(): { g: string; }; }; }; }'.
              Types of property 'd' are incompatible.
                Type '{ e: { f(): { g: number; }; }; }' is not assignable to type '{ e: { f(): { g: string; }; }; }'.
                  Types of property 'e' are incompatible.
                    Type '{ f(): { g: number; }; }' is not assignable to type '{ f(): { g: string; }; }'.
                      Types of property 'f' are incompatible.
                        Type '() => { g: number; }' is not assignable to type '() => { g: string; }'.
                          Type '{ g: number; }' is not assignable to type '{ g: string; }'.
                            Types of property 'g' are incompatible.
                              Type 'number' is not assignable to type 'string'.

Type '{ a: { b: { c: { d: { e: { f(): { g: number; }; }; }; }; }; }; }' is not assignable to type '{ a: { b: { c: { d: { e: { f(): { g: string; }; }; }; }; }; }; }'.
    'a.b.c.d.e.f(...).g' is incompatible between these types because 'number' is not assignable to type 'string'
