bug: Avante does not give diffs that I can apply, it only seems to show the entire file in the side bar

[theahura]

Describe the bug

In a given file, if I ask for something like:

"Add a new function that returns foobar"

Instead of giving a diff, I will get the entire file back, with no ability to actually apply any changes from the sidebar directly. It looks like the system is trying to use tools:

Besides being a huge waste of tokens, this really breaks the workflow of chat --> get change --> apply change --> review change and edit --> chat, since there is no longer a functional apply step for diffs. This problem occurs even if I ask for search replace blocks, as per https://github.com/yetone/avante.nvim/blob/af80a1ad7819f188f093fbb1a7566d324ad9452f/lua/avante/templates/planning.avanterules

I assume something changed with the generation prompts? Note that I have tool_use disabled, and am using gemini.

To reproduce

Open a file with existing code in it, input "Add a new function that returns foobar"

Expected behavior

I would get SEARCH/REPLACE blocks, as before, with just the requested change instead of the entire file diff.

Installation method

Use lazy.nvim:

{
  "yetone/avante.nvim",
  event = "VeryLazy",
  lazy = false,
  version = false, -- set this if you want to always pull the latest change
  opts = {
    -- add any opts here
  },
  -- if you want to build from source then do `make BUILD_FROM_SOURCE=true`
  build = "make",
  -- build = "powershell -ExecutionPolicy Bypass -File Build.ps1 -BuildFromSource false" -- for windows
  dependencies = {
    "nvim-treesitter/nvim-treesitter",
    "stevearc/dressing.nvim",
    "nvim-lua/plenary.nvim",
    "MunifTanjim/nui.nvim",
  },
}

Environment

nvim 0.10.2 Ubuntu 20.04

Repro

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
  spec = {
    -- add any other plugins here
  },
})

Even with the tool use on, I regularly get this error when it tries to use the replace_in_file tool, which it does constantly

Error: {
  code = 500,
  message = "An internal error has occurred. Please retry or report in https://developers.generativeai.google/guide/troubleshooting",
  status = "INTERNAL"
}

IDK what changed, but this has totally broken avante for me

Completely agree with you on the workflow :) Have you tried adding mode = "legacy"

[theahura]

I didn't know that mode existed, I ended up just reverting my entire lock file back 3 weeks 😂 will give that shot when I'm back at my keyboard

+1, this breaks all my workflow. Just try to print all the file again without search/replace blocks. I will try to fix the version for make this works as before :o

[codr1]

Agreed. This is a bit of a disaster... Did we screw up something in the config?

I'm having the same issue in a new install, but in another install seems to be working fine. Probably it is worth mentioning that in the broken one I'm using openai vs the good one where I use deepseek. Is there a way to rollback the version from Lazy?

[a-chacon]

In your config file of avante just set the version as it:

return {
  "yetone/avante.nvim",
  event = "VeryLazy",
  version = "v0.0.23", -- HERE
  opts = {
    provider = "deepseek",

I was using deepseek and this don't works. (I mean with the main changes). But fixing the version works perfect. I just missed one feature that is adding all open buffers to the chat with just one shortcut.

Im getting just errors on that version
