Hello, @zhuojiuya! I'm here to help you with any bugs, questions, or contributions. Let's tackle this issue together while we wait for a human maintainer.

I found a similar issue regarding file uploads in Dify's chatflow HTTP request node. There is a known limitation where file uploads larger than 800KB fail with a 'Server disconnected without sending a response' error. The recommended workaround is to use a Python code node instead of the HTTP request node for handling larger file uploads [1].

Additionally, ensure that the Content-Type is correctly set to multipart/form-data and that all required headers and parameters are included, such as the Authorization header with a Bearer token and the file parameter in the form data [2].

If the issue persists, consider checking the server configuration or network settings, as the HTTP_REQUEST_NODE_MAX_BINARY_SIZE is set to 10MB in the docker-compose.yaml, which suggests that the limitation might be due to other factors [3].

To continue talking to Dosu, mention @dosu.

Then it's not supported in this node, you need to find way to extract them either from iteration node or code node.
