I've gotta be honest here, I don't know of a "messages" field within LM Studio. I also just double checked and, as of LM Studio version 0.3.15, there is no messages field. I can add a system prompt, but it is by no means mandatory (and I am pretty sure it does nothing for Formamorph).
It seems like Formamorph isn't sending the data correctly, so the AI doesn't know how to interpret it. Within LM Studio, can you please turn on Verbose Logging and try another prompt? Maybe that will shed some light on where it's going wrong.
