Describe the bug
Describe the bug:
Avante with gpt4.o is producing an error when attempting to rewrite code. I also verified that I had the latest changes.
To reproduce
File:
<?php
use App\Models\User;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
// This will be replaced with mediumText to store medium-sized text data
// The 'content' column stores large text data related to saved jobs
{
Schema::create('saved_jobs', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->string('source');
$table->string('url');
$table->blob('content');
$table->boolean('hasApplied');
$table->foreignIdFor(User::class)->constrained();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*/
public function down(): void
{
Schema::dropIfExists('saved_jobs');
}
};
Output:
in the selected file add a comment

To add a comment in the specified file, I'll insert a comment above the line where the `content` column is defined. This comment will explain the purpose of the `content` column. Let's proceed with adding the comment.

> great job, now replase blob with mediumText
Let's replace `blob` with `mediumText` in the migration file. This change will allow the `content` column to store medium-sized text data, which is suitable for most use cases where you need to store a significant amount of text. I'll make this change for you now.

It seems there is a persistent issue with the replacement process. Let me try a different approach to ensure the change is applied correctly.

> can you add a comment above blob?
Certainly! I'll add a comment above the line where the `blob` type is defined, explaining that it will be replaced with `mediumText`. Let's proceed with adding the comment.
╭─ insert succeeded
│ running tool

The comment has been successfully added above the `blob` type, indicating that it will be replaced with `mediumText`. If you need further assistance or any more changes, feel free to let me know!
Expected behavior
Expected behavior:
$table->blob should have been replaced with $table->mediumText.
Installation method
Config setup:
-- Suggestions for improving Avante configurations:
-- 1. Customize the 'opts' table to fine-tune the behavior of the Avante plugin.
-- 2. Consider adjusting the 'temperature' and 'max_completion_tokens' for different use cases.
-- 3. Explore additional dependencies that might enhance functionality.
-- 4. Regularly update the plugin and its dependencies to benefit from the latest features and fixes.
-- 5. Review the documentation of each dependency to fully utilize their capabilities.

neovim version: v0.11.0 platform:
Repro
vim.env.LAZY_STDPATH = ".repro"

Same issue with gpt-4.1 too (with copilot as provider). In two of my projects, one being plain javascript and the other being nuxt 3, this error does not occur on the plain javascript project.
I'm running on Mac M3, nvim v0.11.1
Same issue with gpt 4o and 4o-mini of fedora linux. Unfortunately cannot use avante, just to write a new file
I've tried using other providers as well, and they all fail. Some of the providers I've tried:
Ollama
- Qwen3
Copilot
- GPT-4.1
- GPT-4o
- GPT-4o mini
- Gemini 2.0 Flash
- Gemini 2.5 Pro
- o3-mini
- o4-mini
Azure
- GPT-4.1
Sometimes (rarely), it hits, tried to make it add a comment at the beginning of a file, and after 1 failure (no diff block found), it got it. But all the other times, the same error occurs. I've also tried to delete ~/.local/state/nvim/avante/*
Other tools like view or actions from MCPHub works fine.
I've added a couple of debug files in case it helps.
10-request-body.json 10-response-body.txt
For now, I just inform the LLM to not use the replace_in_file tool. Seems the write_in_file is working.
I started to get this error since yesterday. Avante feels broken and I cannot do anything with it any more sadly. This was reported more than a month ago and I use Avante every day. Not sure what happened.
I just open a PR #2438. This may fix the replace_in_file error for some models.
Even though @kylix31 PR has merged, this error still happens using copilot/claude-sonnet-4 for me
After my merge, something new was broken some tools. But now, it was fixed #2469

Still happens to me with Gemini:
