Generating features failure

Hello, I am trying to generate features (using an impulse with spectral analysis and keras) but for some reason i keep getting the following error:
"Creating job… OK (ID: 1632011)

What could cause this?

Hello @StardustTiger,

It seems that you set your project type as an Object Detection one:

Can you please change Bounding Boxes to One label per item please under the Dashboard?
