ArcGIS Pro: Image segmentation

[@DCARA06]

what is this band extraction step? What type of imagery is this? What are the bands 4,3,1? Are they red, green and blue?

Thanks, the video is not useful without your steps.

Why did you skip over the band extraction step? Doesn't seem to work for me.

Thanks for your helpful video.
I am attempting supervised and object-based image classification using Arch Pro (V.3.2). Here are the steps I have followed:
I acquired Sentinel-2 imagery and combined bands 2, 3, 4, and 8 (10m resolution).
I performed image segmentation.
I created a classification schema.
I generated training samples.
However, when I attempt to classify using a support vector machine classifier, I encounter the following error:
ERROR 003436: No training samples found for these classes: Soil, Water, Impervious, Grass, Tress.
The table was not found. [VAT_Segmented_202407110934456475089_interIndex]

I have tried several times but haven't been able to identify the cause of this error. Do you know what might be causing it?
