Hi Dan,


Thank you for this feedback. This error message is a generic one, we're working on improving our error messages to make them more actionable.


For your model, we need to know a little bit more details in order to help you troubleshoot. Can you let me know your orgid?

Hi @Anonymous ,

The reason why you met this problem is that not all your data meet the requirement of AI builder.

When you are training a model, system will filter useless,duplicate data and the data that not meet rules automatically.

Collecting data in this way could improve the effectiveness of your data and your model will be more accurate.

For now, you could not check which data was filtered by system automatically in PowerApps.

I suggest you express your views about adding this function on PowerApps Ideas Forum. Your precious feedback will be very helpful for our work.


What's more, different model have different rules about data, you could check this to see details:
