dynamic slice attributes are not allowed

[idaymand]

i have a detect model .onnx format. I use it in project onnxruntime-web-demo from Microsoft, all works for me well.

I do a simple project in angular 9, and same model with same code doesn't work for me. I don't pass step
const outputData = await model.run(feeds);
i get error

app.component.ts:121 Error: dynamic slice attributes are not allowed
