openclaw - 💡(How to fix) Fix [Bug] 3.24版本模型多次传递空参数导致工具调用失败 [1 comments, 2 participants]

Fix Plan

To address the issue of multiple empty parameters being passed to tools, we need to modify the tool calling implementation in OpenClaw 3.24.

Step-by-Step Solution:

1. Check and Update Tool Calling Implementation: Review the new tool calling implementation to ensure it correctly handles parameter passing.
2. Validate Model Function Calling Format: Verify that the function calling format for affected models (Kimi K2.5 and MiniMax M2.7) is correctly parsed.
3. Implement Parameter Validation: Add checks to ensure that parameters are not empty before passing them to tools.

Example Code Snippet (Node.js):

// Before calling a tool, validate parameters
function callTool(toolName, params) {
  if (!params || Object.keys(params).length === 0) {
    throw new Error(`Empty parameters for tool ${toolName}`);
  }
  // Proceed with calling the tool with validated parameters
  // ...
}

// Example usage:
try {
  const params = { /* parameter object */ };
  callTool('exec', params);
} catch (error) {
  console.error(error);
}

Verification

To verify the fix, test the tool calling functionality with various parameters, including empty ones, to ensure that the implementation correctly handles these cases and does not pass empty parameters to tools.

Extra Tips

• Regularly review and test changes to the tool calling implementation to prevent similar issues.
• Consider adding automated tests to cover different scenarios, including edge cases like empty parameters.
