big error message when opening a `.v` file using neovim

Whenever I open a `.v` file, I get this error message: ```text Error detected while processing VIMINIT..script /nix/store/8yyh0841ypqyp90s3bjbzqkszjgxkmr1-mnw-configDir/init.lua: E5113: Error while calling lua chunk: vim/_editor.lua:0: VIMINIT..script /nix/store/8yyh0841ypqyp90s3bjbzqkszjgxkmr1-mnw-configDir/init.lua..nvim_exec2() called at /nix/store/8yyh0841ypqyp90s3bjbzqkszjgxkmr1-mnw-configDir/init.lua:0[1]../nix/store/lpvd9jcq8k518mrafh2srw9a41cdavyd-neovim-unwrapped-0.11.6/share/nvim/runtime/syntax/syntax.vim[44]..BufReadPost Autocommands for "*.v"..FileType Autocommands for "*"..function <SNR>1_LoadFTPlugin[20]..script /nix/store/y1xlz2vha6lnvz5py9vg2kj5bzbvrajd-vimplugin-Coqtail-1.8.0-unstable-2026-02-04/ftplugin/coq.vim, line 9: Vim(if):E121: Undefined variable: g:coqtail#supported stack traceback: [C]: in function 'nvim_exec2' vim/_editor.lua: in function 'cmd' /nix/store/gz67kpjzcfs941b7j211hhwdb26sii37-init.lua:64: in main chunk [C]: in function 'dofile' .../8yyh0841ypqyp90s3bjbzqkszjgxkmr1-mnw-configDir/init.lua:5: in main chunk Error detected while processing BufReadPost Autocommands for "*": Error executing lua callback: ...-neovim-unwrapped-0.11.6/share/nvim/runtime/filetype.lua:36: BufReadPost Autocommands for "*"..FileType Autocommands for "*"..function <SNR>1_LoadFTPlugin, line 2: Vim(execute):E730: Using a List as a String stack traceback: [C]: in function '_with' ...-neovim-unwrapped-0.11.6/share/nvim/runtime/filetype.lua:35: in function <...-neovim-unwrapped-0.11.6/share/nvim/runtime/filetype.lua:10> Error detected while processing BufReadPost Autocommands for "*.v"..FileType Autocommands for "*"..function <SNR>1_LoadFTPlugin: line 2: E730: Using a List as a String Error detected while processing BufReadPost Autocommands for "*.v"..FileType Autocommands for "*"..function <SNR>1_LoadFTPlugin[20]..script /nix/store/y1xlz2vha6lnvz5py9vg2kj5bzbvrajd-vimplugin-Coqtail-1.8.0-unstable-2026-02-04/ftplugin/coq.vim: line 9: E121: Undefined variable: g:coqtail#supported line 24: E121: Undefined variable: g:coqtail#supported line 32: E121: Undefined variable: g:coqtail#supported E349: No identifier under cursor ``` Please let me know what else information you want about my setup to help debug this.
