Trying to implement file uploads in our custom Kotlin Android app using the Genesys Cloud Web Messaging SDK. We’re hitting a wall with image files. The sendFile method works for PDFs but silently fails for JPEGs without throwing an exception. Are there hardcoded MIME type restrictions in the Android SDK v2.14, or is this handled by the guest API endpoint? Need to know if we need to pre-validate content types before calling the SDK.
