uncaughtException Error: write EPIPE about coc-pyright HOT 11 CLOSED

Thank you for your report, but I can't reproduce this. What's your coc.nvim version? You can get it from :CocInfo.

The write EPIPE means write date to a closed connection, maybe something broken between the client and server.

from coc-pyright.

I just updated the plugin and have the same error.

coc.nvim version: 0.0.82-d1568d56 2023-09-29 19:43:34 +0800

from coc-pyright.

Does the pyright process exist while you encounter this error message?

from coc-pyright.

[Info - 13:45:42.604] No source files found.

Strange log, pyright didn't find any Python files in your project.

Do you have some root patterns files, for example .git/, pyproject.toml, pyrightconfig.json file in your project root?

from coc-pyright.

pyright is running /opt/homebrew/Cellar/node/21.2.0/bin/node --max-old-space-size=3072 /Users/jayed/.config/coc/extensions/node_modules/coc-pyright/node_modules/pyright/langserver.index.js --node-ipc --clientProcessId=45713

I understand the "no source files found" error now. The file doesn't have a .py extension. When I rename it to include the extension, 1 source file is found, however the [coc.nvim]: Uncaught exception: write EPIPE error still exists.

I have a number of root patterns

['.git', '.env', 'venv', '.venv', 'setup.cfg', 'setup.py', 'pyproject.toml', 'pyrightconfig.json']

however this is an incredibly simple project with one text file, one python file, one tags file, and a .git directory

from coc-pyright.

Do you have any other extensions? Make a minimal test, maybe the error isn't came from coc-pyright.

from coc-pyright.

I receive the error with only pyright

installed

from coc-pyright.

It also happens with a minimal vimrc

let mapleader = ";"

map <leader>e :e ./init.vim<CR><C-W>
map <silent><leader>E :source ./init.vim<CR>:filetype detect<CR>:exe ":echo 'init.vim reloaded'"<CR>

set runtimepath+=$HOME/.vim/

call plug#begin('$HOME/.vim/plugged')
Plug 'neoclide/coc.nvim', { 'branch': 'release' }
call plug#end()

If, however, I change from iTerm2 to the macOS Terminal the error goes away

from coc-pyright.

It's not coc.nvim or coc-pyright issue, but something broken in your env.

from coc-pyright.

I'm also experiencing this issue in iTerm2 on macOS.
