system's content is blank

[vicliu624]

when i use IF_AI_tools.json to test. In IF_Chat_Prompt, engine is 'lmstudio' and tool is 'None'.
but server log show
[2024-08-04 00:03:05.289] [ERROR] [Server Error] {"title":'"messages' array must only contain objects with a 'content' field that is not empty"}
in LM Studio.

The reason is content is "", when role is system.

right maybe did you select assistant none? this looks like a bug I made somewhere but meanwhile maybe you can create a new preset that says something like "you are a helpful assistant" or use the prime directives
