+Issue: PaiEasChatEndpoint._call_eas should return bytes type instead of str type
+Explanation: To understand the issue, we first need to know the content of the method in the codebase. Therefore, we search the symbol `def _call_eas` in the cloned repo langchain. 
+
+```python
+from metagpt.tools.libs.editor import Editor
+
+# Initialize the Editor tool
+editor = Editor()
+
