The exception should contain additional information. The three most likely issues are:

1. API Key is incorrect or absent
2. API Key does not match the region for which you have access (check the API URL in the Azure portal, and create the EmotionServiceClient using the constructor that takes two arguments).
3. Image is invalid or not supported
