I'm very new to neovim and I'm trying to set it up for LaTeX. I've been unable to indent in .tex files after changing tabstop and shiftwidth after using :set to set them both to 4. Specifically, my setup and what I've done are as follows:

Setup:

Install neovim and used kickstart.nvim.
Installed vimtex and vim-dispatch (following supercharged LaTeX using neovim)
Changed tabstop and shiftwidth to 4 using :set.

To reproduce issue:

Create a new .tex file.
Enter insert mode and press tab.
No indenting occurs, and I get the following error:

Error executing vim.schedule lua callback: ...al/share/nvim/lazy/LuaSnip/lua/luasnip/nodes/snippet.lua:1054: attempt to call method 'indent' (a nil value)
    stack traceback:

This issue does not arise with normal .txt files (i.e., I can entire insert mode and indent empty lines as expected). I've tried adjusting tabstop back to 8 and reinstalling neovim, but the issue persists.

Any help would be greatly appreciated.

My mistake was in a completely different place. In my ~/.config/nvim/LuaSnip directory, I had a tex.lua file which contained the following snippet:

s({ trig = '^', regTrig = false}, { fmta('_{<>}', { i(1) }) }),

I removed the extra pair of parentheses:

s({ trig = '^', regTrig = false}, fmta('_{<>}', { i(1) }) ),

and the error went away (after also fixing the trigger on the magic character ^).
