Receiving error message, "Couldn't load data. Try again later.", when using AI Builder custom model for category classification

Hi there, I have been facing this error message (in the screenshot) when I try to use a custom model for category classification - "Classify texts into custom categories". Any help on this will be appreciated!

Did you retry later? This could be due to a temporary outage.

If the problem still occurs, what is the size of the dataset in your training table?
