Steps to reproduce

  1. Agent nodes in chatflow applications are unable to select Doubao-1.5-pro-32k that supports FunctionCalling
Image

✔️ Expected Behavior

  1. Fix this bug and support selecting Doubao-1.5-pro-32k

❌ Actual Behavior

  1. first，Doubao-1.5-pro-32k supports FunctionCalling

Image

  1. The agent node cannot select Doubao-1.5-pro-32k, and the Doubao model is not displayed at all
Image
  1. According to the verification data, due to the lack of tool call in the configuration, it cannot be selected, but obviously this is incorrect because Doubao-1.5-pro-32k supports FunctionalCalling

@wilche2 Hello! I'm here to help with any bugs, questions, or contributions. Let's work together to solve the issue you're facing.

Agent nodes in chatflow applications cannot select the Doubao-1.5-pro-32k model because it does not meet the specific model compatibility requirements in the Agent plugin. In Dify, only models that support either 'function call' or 'ReACT' methods for tool interaction can be used in workflow agent nodes. The system checks the model's features to determine if it supports the necessary strategies, such as FUNCTION_CALLING. If the model schema does not include features like MULTI_TOOL_CALL or TOOL_CALL, it will not be available for selection in workflow agent nodes [1][2].

The official page of volcengine shows support for Function Call, isn't it the same as Function Calling??
