Hi, maybe this can help you. I had issues with the application when using /verify with the nose challenge. To fix it I needed to go to the nose.py file and add the condition for the 'residual' variable:

_, residuals, _, _, _ = np.polyfit(nose_trajectory_x, nose_trajectory_y, 2, full=True)
if not residuals:
    residuals = 0
trajectory_error = math.sqrt(residuals / len(context['nose_trajectory']))

in the nose_state function.

Hi

I ran into same issue as well.
Double slash URL can be fixed with changing the endpoint variables in source/client/.env file.
Original:
REACT_APP_API_START_ENDPOINT=/challenge
REACT_APP_API_FRAMES_ENDPOINT_PATTERN=/challenge/{challengeId}/frame
REACT_APP_API_VERIFY_ENDPOINT_PATTERN=/challenge/{challengeId}/verify
Replaced
REACT_APP_API_START_ENDPOINT=challenge
REACT_APP_API_FRAMES_ENDPOINT_PATTERN=challenge/{challengeId}/frame
REACT_APP_API_VERIFY_ENDPOINT_PATTERN=challenge/{challengeId}/verify

But even with these changes, CORS issue still remains. I also enabled CORS on every endpoint on API Gateway.
I have also checked Chalice routes and all endpoints have cors=True as parameter.

Any chance on fixing this issue?
