Some models deployed locally can be used normally in Chat with Notebook, but some models may experience Failed to send messages, such as Qwen3-32B

same here. Has this issue been resolved yet? how?

Here, the document content from source will be provided to the LLM together, which may exceed the context length of the model. Switching to a model with a larger context window should solve the problem

Hi everyone, trying to isolate the issue for us to fix. Can you help em with some information?

• Does the error only happen in Ollama?
• Can you tell me what's the token count in the bottom right window when it fails? Does it fail if you use no content or small contents or only when you use large contents?
• Does the error also happen on smaller models? Like qwen3:8b or does it happen in all models

We'll get to the bottom of it and fix it.

vLLM+Qwen3-8B, open-notebook v1.2.3 , have the same problem!

Same problem here, but with a small addition: "Ask" works well.

Alright.. I just pushed a new version 1.3.0 (tagged latest). Can you guys check that as well? Sorry.. I just can't repro on my end. @mindofillusion @fast1212
