title: Operation returned an invalid status code: 'NotFound'
body: <p>I actually trained the model of custom vision to detect vehicles and i want to detect them in real time, so i tried to run the sample app available in github <a href="https://github.com/microsoft/Cognitive-Samples-VideoFrameAnalysis" rel="nofollow noreferrer">https://github.com/microsoft/Cognitive-Samples-VideoFrameAnalysis</a> , but i always get this error : Operation returned an invalid status code: 'NotFound', it says on the internet that i didnt specify the concerned iteration, but i didnt find where to do it in the sample app, they also suggested to set the iteration as default but i didn't find this option in custom vision configurations.</p>
