              sectionItemCode: y.code,
              answer: y.answer
            };
          } else {
            delete this.data.answers;
          }
        })
      };
      this.pushData(this.data);
    });
  }

could you let me know how to solve this error? 'Not all code paths return a value.' Thank you.

Add a return y (or undefined, or anything else conform your other return) after delete this.data.answers;. You're using map so you need to return an object that gets mapped back. If you don't want or need to return anything then return undefined so it'll disappear.
