If the printed data is res.data.rows[0].bookImages, it is the original data.
But if res is printed, the printed bookImages data has been processed later.
What is the reason for this?
The res data did not change when I printed it. Is it just caused by console.log? Or is it due to asynchrony or an object reference problem?
My suggestion is that you check this.pukr.parseImage method. The input in this method should be consistent with the data in console.log(res).
