The attribute 'total' is missing in the input example set.

Hi @mgrabczewski,

Just so I'm understanding the problem correctly, the issue is that you get this pop-up before running the process, but the process runs successfully?

Thanks,

Roland

Yes, process works very well, but I wonder if the pop-up can be somehow removed for visual reasons.

So the pop-up is because the metadata hasn't reached that operator, so it doesn't know there's an ExampleSet there. What I can suggest is that you enable this option:

After the first run, it should then stop producing this pop-up. I will also investigate whether there's any other options.

Best,

Roland

Great! That's exactly what was needed!

Thanks,
