Hi! What does the data look like that you're streaming in? Does it have all the fields required for the interface, e.g. "image" with a URL or the base64-encoded data for the image_manual block or a "text" and "tokens" for ner_manual?
Ah okay, that makes sense. If your images are quite large, you might want to resize them before loading them in (or run a losless compression over them if you're not doing that already).
