SystemMessage too large.

[fmatar]

  @SystemMessage(value = "", fromResource = "large_prompt.txt")
  String chat(@MemoryId String cid, @UserMessage String userMessage);

If the file is large (mine is around 87kb) I get the following exception.

We should fix this, but I'll just note that using such a huge prompt as a system or user message is almost certainly not a good idea

[jmartisk]

Why is this being recorded at all, shouldn't the system message be overridable at runtime?

[fmatar]

I got around it by setting the SystemPrompt to a variable.

@SystemMessage="{system_prompt}"

And then in my @PostConstruct I'm setting the prompt as a global variable.

Not the usual approach for doing thing however this specific prompt is dictated by a massive schema definition.

No, it's not
