When developing vue2.

export const waterFallPlaceholder = e => {
    e.src = "../../images/WaterFallBanner.png";
    e.onerror = null;
    return e.src;
}

Then I struggled to find the problem. I inadvertently converted the relative path image into a base64 image, and the problem was solved. Since I don’t know much about base64, could you please tell me what the root of this problem is.
