Hello @lyq518! I'm here to help you with any bugs, questions, or contributions you may have for Dify. Feel free to ask for assistance while waiting for a human maintainer.

I found a similar issue related to newline characters in JSON data within the HTTP request node. The issue titled 'Newline' not escaped when passed as string to HTTP request was closed, and the suggested solution was to manually escape newline characters in your input data or verify how the server interprets the received JSON payload. This ensures that newline characters are correctly understood by the server, aligning with the JSON specification's requirements for character escaping [1].

Additionally, the HTTP request node in Dify handles JSON data by parsing it through the _init_body method, where newline characters are managed by the json.loads function, which correctly parses them as part of the JSON data structure [2].

If you're experiencing issues with newline characters in version 0.10.2, you might want to check if the JSON data is being correctly formatted and escaped before being processed by the HTTP request node.

To continue talking to Dosu, mention @dosu.
