Hello @profonline! I'm here to help you with bug reports, answer questions, and assist you in becoming a contributor. Let's work together to resolve any issues you may be experiencing.

The "Model schema not found" error in Dify's agent module typically occurs when the model_schema is not retrieved or lacks necessary features. This can happen if the get_model_schema method of the LargeLanguageModel class returns None or an empty schema for the specified model and credentials. Additionally, ensure that the model instance is of type LargeLanguageModel, as the error can also be raised if it is not ^[1][2].

To resolve this issue, verify that the get_model_schema method is correctly implemented for the smollm model and that it returns a valid schema. Also, ensure that the model instance is properly configured as a LargeLanguageModel.

I got the same error in agent only. It is new bug?

This error is raised by these line.

Can you guys provide the settings of the model in orchestration page and settings page.

How can I solve this problem via UI? As Dify does not allow me debugging it via code level.

Please provide the necessary information as I mentioned above.

same error

Hello @crazywoola,

I'm encountering the same error specifically with my Llama models. I am using Together AI as the provider for these models, and I have kept the default settings.
dify version = 0.14.2

I encountered the same error - "Model scheme not found" in agent with Qwen and Mistral model. I did not try other but I expect the result should be the same. Thanks!
Remark: I upgraded to 0.15.1 but the error is the same.

This error is raised by these line.

dify/api/core/app/apps/agent_chat/app_runner.py

Lines 205 to 206 in 56e15d0

	if not model_schema or not model_schema.features:
	raise ValueError("Model schema not found")

Can you guys provide the settings of the model in orchestration page and settings page.

Hello @crazywoola , I am beginner level. I do not know the exact setting you want. I copied the setting file here.
.zip Thank you!

same error when I use agent and ollama

Hello @JiweiZh , you save me! Thank you very much! 😘💕

If it is a newly added agent, you cannot select the disable function call model at all

Edit the file '/app/api/core/app/apps/agent_chat/app_runner.py' in the docker-api container and delete the code in the red box. When using an OpenAI-API-compatible LLM that does not support Function calling, Stream function calling, and Vision, the features array will be empty.

If it is a newly added agent, you cannot select the disable function call model at all

The function call is enabled in the model setting directly. It is not related to the agent.

Hi, could you please tell me how to do it?

The agent needs llm to have an inference mode,the function call is one of the inference modes,So it's relevant.

let me solve this error directly
