Images can't be uploaded to Teachable Machine: File Input Error

[somdipdey]

I am using the dataset (Fruits-360) for fruits' classification. The dataset is available here: https://github.com/Horea94/Fruit-Images-Dataset

When I am trying to upload the dataset for each fruit classes, the uploading works for some classes such as Apple Braeburn, Apple Golden 1, but doesn't work for many other classes such as Apple Pink Lady, Apple Red 1, etc. The platform is throwing the error: File Input Error, when I try to upload the images on https://teachablemachine.withgoogle.com/train/image

Any idea why this might be happening? How can I fix it?
