Treesitter error when running in kotlin

[mairs8]

I am getting the below error when trying to run the plugin with kotlin. Note that the error doesn't appear to be with tree-sitter as it works fine when i remove the nvim-dap-virtual-text plugin.

What is the output of :check health nvim-treesitter? Are you sure you where using tree-sitter highlighting before on kotlin files? Nvim has a lua function to inspect tokens under cursor(:Inspect if I remember correctly)

Are you sure you where using tree-sitter highlighting before on kotlin files?

Now that you mention it, my treesitter highlighting appears to have stopped working altogether....

Nvim has a lua function to inspect tokens under cursor(:Inspect if I remember correctly)

sorry i have no idea what you mean (new to neovim). can you please elaborate?

i have tried running the same on go and getting the same error. below is the healthcheck output on my go file:

@theHamsta You're right, the go parser wasn't installed. Running :TSInstall go fixed it. The only issue that i had to imperatively install go this way. do you know what i can add to install decoratively in my plugin.lua files?

[ColinKennedy]

Just wanted to chime in, I get this error whenever nvim-dap jumps to an assembly file. I get this error

My :checkhealth nvim-treesitter reads all clear

I've forked nvim-dap-virtual-text for the time being with this fix, which appears to be working

virtual_text.lua

  if vim.treesitter.get_parser and vim.treesitter.language and vim.treesitter.language.get_lang then
      lang = vim.treesitter.language.get_lang(vim.bo[buf].ft)
-     parser = vim.treesitter.get_parser(buf)
+     if lang ~= nil then
+       parser = vim.treesitter.get_parser(buf)
+     end

[sashomasho]

I have the same problem with Java when stepping through .class files, I'm not sure what is the problem, since neovim filetype is set to java, but in the snippet from the previous post vim.bo[buf].ft is null. I'm pretty sure this was working before.

[xebcam]

It would be interesting if there were a way to disable nvim-dap-virtual-text for certain filetypes, so that when the filetype is null, it won't complain.
