What is the correct format for the API SurveyQuestionImage.Data field?
问题 I am working with the GCS API, attempting to create a survey with image data. I am using the NuGet package Google.Apis.ConsumerSurveys.v2 version 1.14.0.564 on the .Net platform. I can create surveys that do not contain image data without problem. However, when I try to create a survey with image data I receive an error from the API. I have on hand base64 encoded png format image data. My images display properly in an IMG tag on a web page when the src attribute is set to 'data:image/png
