Steps to reproduce
An error occurred using the default code parser tool call
✔️ Expected Behavior
No response
❌ Actual Behavior
No response
To resolve the issue of a missing tool parameter instruction in the tool config when using the default code parser tool with the "FunctionCalling" strategy and "qwen-max" model in a self-hosted Docker environment, ensure that the tool parameter is correctly initialized and provided in the configuration. Here's what you can do:
-
Check Tool Configuration: Make sure that all required parameters for the code parser tool are specified in the tool configuration. The required parameters are:
language: Must be specified as "python3" or "javascript".code: The code to be executed, ensuring it only uses native packages and avoids network/IO operations [1].
-
Initialization Function: The function
init_frontend_parameterchecks if the parameter value is provided. If not, it uses a default value. If the parameter is required and no value is found, it raises aValueError. Ensure that:- The tool parameter is specified in the tool configuration.
- If the parameter is required, it must be present; otherwise, ensure a default value is set in the
rule.default[2].
-
Runtime Parameters: Ensure that runtime parameters are correctly defined in the tool's implementation. For example, in the
VectorizerToolclass, theget_runtime_parametersmethod defines required parameters. Make sure your tool's parameters are similarly defined and included in the configuration [3].
By following these steps, you should be able to resolve the missing tool parameter issue in your configuration.

language: Must be specified as "python3" or "javascript".必须指定为“python3”或“javascript”。code: The code to be executed, ensuring it only uses native packages and avoids network/IO operations [1].执行代码，确保它仅使用本地包并避免网络/IO 操作Initialization Function: The function
init_frontend_parameterchecks if the parameter value is provided. If not, it uses a default value. If the parameter is required and no value is found, it raises aValueError. Ensure that:初始化函数：函数init_frontend_parameter检查是否提供了参数值。如果没有提供，则使用默认值。如果参数是必需的且未找到值，则引发ValueError。确保：Runtime Parameters: Ensure that runtime parameters are correctly defined in the tool's implementation. For example, in the
VectorizerToolclass, theget_runtime_parametersmethod defines required parameters. Make sure your tool's parameters are similarly defined and included in the configuration [3].运行参数：确保在工具实现中正确定义运行参数。例如，在VectorizerTool类中，get_runtime_parameters方法定义了必需的参数。请确保您的工具参数以类似方式定义并包含在配置 [3] 中。By following these steps, you should be able to resolve the missing tool parameter issue in your configuration.按照这些步骤操作，你应该能够解决配置中缺少工具参数的问题。

这个工具是dify官方提供的，工具有参数描述和是否自动生成的开关
I have the same question, if I build an agent directly, this agent can use all tools whether the tools are original or I build. However, when I tried to create an agent in the workflow, it always showed the same problem as yours
I also encountered this issue at the beginning. After filling in the instructions and queries separately, I can now add and run an Agent in Chatflow without problems. Version 1.1.3
Have you added any custom tools? Could you provide a prototype of an interface function (without content) and the tool definition in JSON format?
@Iceblue76ec
I'm having the same issue. I'm using Dify 1.1.3 with docker and I'm getting an error when using the Agent.

I am getting this error even though I am not using a custom tool and am using the Currenttime tool with the default Agent in the Market.
How do I solve this?
