Steps to reproduce

when I last added the picture to the chat, pressing enter directly shows that the input cannot be empty,
When I uploaded the image to the chat last time, pressing enter directly showed that the input cannot be empty. When I tested the input box with the following workflow and replied directly with "test empty", the test also showed that the question cannot be empty

Image

✔️ Expected Behavior

When the input box is empty and the uploaded file or image is not empty, the question can be asked normally

❌ Actual Behavior

As long as the input box is empty, whether uploading images or documents, the question cannot be left blank

@dosubot[bot] commented on GitHub (Mar 31, 2025):

The reason you can't send a message when the chat input box is empty, even if you have uploaded an image or document, is due to the logic in the ChatInputArea component. The handleSend function checks if the text input is empty or only contains whitespace, and it also verifies if any files are still uploading. If either condition is true, it prevents the message from being sent and notifies you to either wait for the file upload to complete or to enter a message in the input box [1].
