Setting "Format" property in a GenerateRequest causes response to come back empty.

[Caffiendish]

Really, as per title.

I've been unable to set literally anything for Format in a GenerateRequest and have the response come back with anything, not even just "json", but the exact same system message, prompt, model, and format set to "json" as a "Chat" (with chat.SendAsync) returns data exactly as expected.

Literally the only change is swapping GenerateRequest for Chat, to get a successful response from Ollama.

Ollama version: 0.13.5
OllamaSharp: 5.4.12

I might have the same underlying issue with "GetStreamingResponseAsync" using "IChatClient".
There seems to happen a lot in the background (regarding usage of CPU, GPU, RAM), but the response is empty.
