Encountering "Edit Unsuccessful" Repeatedly
Description
Description
When running a large task, it first reads many files, and the reading process works normally. However, once it starts modifying the files, all operations fail with the following error message:
Edit Unsuccessful
Failed to parse apply_diff XML: Failed to parse XML: StopNode is not closed.
I am using the free model X-ai / Grok Code Fast 1.
i got in the past 2 days all updated vscode and kilo extension this error, any solution ?
I have the same issue. the editing tools are poor performance and low success rate in kilocode and all other forks.
Same +1. BTW, it seems that when the context exceed 128k the problem occurs.
i m also getting it from now on, I think only in pycharm it is coming not in vs code
I have the same issue, also on Grok Code Fast 1, on WebStorm as JetBrains plugin v4.112.1, even with context sizes at around ~50-60k this occurs. Usually this doesn't happen for new tasks/chats, but starts happening after additional user messages.
This also happens for grok-4.1-fast-reasoning, on WebStorm with Kilo Code plugin v4.124.0
This somehow makes the model think it's successfully editing the file and will continue editing other files and/or updating the todo list. If you need more info, please let me know I'll be happy to provide it! You can also reach me on kilo code's discord server.

[apply_diff] Result:
The tool execution failed with the following error:
<error>
Missing value for required parameter 'args (must contain at least one valid file element)'. Please retry with complete response.
# Reminder: Instructions for Tool Use
Tool uses are formatted using XML-style tags. The tool name itself becomes the XML tag name. Each parameter is enclosed within its own set of tags. Here's the structure:
<actual_tool_name>
<parameter1_name>value1</parameter1_name>
<parameter2_name>value2</parameter2_name>
...
</actual_tool_name>
For example, to use the attempt_completion tool:
<attempt_completion>
<result>
I have completed the task...
</result>
</attempt_completion>
Always use the actual tool name as the XML tag name for proper parsing and execution.
</error>
...
EDIT: It seems that when enabling https://kilo.ai/docs/features/experimental/native-function-calling and updating to 1.125.1 (priliminairy for me) resulted no more editing errors occurring!
You can set it in the Providers tab of Kilo Code settings and open the Advanced settings section of any Grok model, specifically Tool Call Style, where JSON means "native" 🤓
