Minimal Config

null-ls-config.lua

issue only with prettier plugin

local null_ls = require("null-ls")

null_ls.setup({
    sources = {
        null_ls.builtins.formatting.prettier,
        null_ls.builtins.formatting.black,
        null_ls.builtins.formatting.gofmt,
        null_ls.builtins.formatting.shfmt,
    },
    on_attach = function(client, bufnr)
        if client.supports_method("textDocument/formatting") then
            vim.api.nvim_clear_autocmds({ group = augroup, buffer = bufnr })
            vim.api.nvim_create_autocmd("BufWritePre", {
                group = augroup,
                buffer = bufnr,
                callback = function()
                    -- on 0.8, you should use vim.lsp.buf.format({ bufnr = bufnr }) instead
                    vim.lsp.buf.format()
                end,
            })
        end
    end,

})

### Steps to Reproduce

1) create new file in reactjs project
2) write some code 
3) then save this document
4) again write some more code in this file
5) then press ESC key , to go back to normal mode , here the issue you will see

note : the issue is code duplication.

### Reproducibility Check

- [ ] I confirm that my minimal config is based on the `minimal_init.lua` template and that my issue is reproducible by running `nvim --clean -u minimal_init.lua` and following the steps above.

### Expected Behavior

i expect to format document while saving.

### Actual Behavior

But the problem is , it automatically duplicate code exponentially while go insert mode to normal mode.
