Hello @udit050500! 👋

I'm Dosu, a friendly bot here to assist you with your Langflow issues. While you're waiting for a human maintainer, consider me your bug-busting buddy. Let's tackle this head-on together, shall we? 🤖 🐛

Based on the information provided, it seems like the ChatMessagePromptTemplate is expecting a role field which is not being provided. However, without more context or a clear definition of ChatMessagePromptTemplate in the Langflow codebase, it's challenging to provide a definitive solution.

The error message suggests that the role field is required for the ChatMessagePromptTemplate. You mentioned that you passed role as Jedi, but the error still persists. This could mean that the role field is not being correctly recognized or assigned.

Unfortunately, I couldn't find explicit definitions or requirements for ChatMessagePromptTemplate in the Langflow repository. It would be helpful if you could provide more information about where ChatMessagePromptTemplate is defined in your code or how you're using it. This could help in identifying the issue.

Also, please ensure that the role field is being correctly assigned and that there are no typographical errors or case-sensitivity issues. If the problem persists, it might be a good idea to check if there are any recent changes or updates in the Langflow codebase that might have affected the ChatMessagePromptTemplate.

I hope this helps! If you have any more questions or need further clarification, feel free to ask.
