Hello, @fakers777! I'm here to assist you with any bugs, questions, or contributions. Let's work together to resolve your issue.

The issue you're experiencing with redundant newline characters in the model output might be related to how the OutputPanel component processes these outputs. In Dify, the OutputPanel component handles newline characters by joining array elements with newline characters when the output is an array of strings. This is done using the join('\n') method [1].

If the output is not intended to have newline characters, you might need to adjust the processing logic to trim or remove these characters after the model output is received. This could involve modifying the component or adding a utility function to clean the output string before it is displayed or used further.

To continue talking to Dosu, mention @dosu.
