error: nvim_echo must not be called in a lua loop callback

[avsej]

I've configured using defaults from readme. Neovim version: https://github.com/neovim/neovim/commit/beca82721

Error executing luv callback:

Hi, that's weird, I am on nightly and I have not encountered this error. Did you build Neovim from scratch on that commit? Could you post your nvim --version?

[powerblo]

Hey, I've encountered the same error, here's my nvim version.

NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1702233742

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/usr/share/nvim"

Run :checkhealth for more info

Same error here, on nvim v0.10.0-dev-1390+gf1775da07

Since I am unable to reproduce, I can not really fix it properly, but I created a branch and would ask you to try to examine it, then we'll see if it's fixed! add the following line to the lazy setup:

branch = "fix/echo-loop"

Thanks!

[vlimki]

Hey, thanks for the quick response! Unfortunately, it did not fix it for me.

I tried to do some inspection myself and commenting out the line in utils.lua:

function M.log_info(str)
    -- vim.notify(str)
end

fixed it for me. Works great now! Not sure what's happening under the hood, but this is the error I get when the line is not commented out:

[arminveres]

Hi there, I updated, force pushed, to the fix/echo-loop branch, could someone check, if the issue persists? I wrapped the vim.notify call into a pcall therefore if there is an error, it is suppressed. @vlimki @avsej @powerblo

Just attempted the fix/echo-loop branch, chiming in to say that the fix works perfectly for me.

[powerblo]

fix/echo-loop works well with nvim v0.10.0. Thanks a lot!
