问题 I get different results when using a model to get image annotation predictions from web UI and from API. Specifically, using the web UI I actually get predictions, but using the API I get nothing - just empty output. It's this one that gives nothing using the API: https://cloud.google.com/vision/automl/docs/predict#automl-nl-example-cli Specifically, the return value is {} - an empty JS object. So, the call goes through just fine, there's just no output. Any hints as to how to debug the issue
