Hey 👋

Thanks for reporting, but that is not a minimal config.

Closing for now.
Feel free to reproduce with a minimal config as requested in the issue template + troubleshooting section and then reopen. 😀

[braxtons12]

I don't have a minimal config for this (yet, will try to put one together this weekend if original reporter doesn't beat me to it), but want to say I'm also experiencing this on Arch Linux w/ the latest nvim nightly.

The problem occurs when first opening a Rust file and a very similar (line 26 instead of 46) problem occurs when running :RustLsp debuggables

Lock the version for now to avoid this problem.

Caused by: rust-lang/rust-analyzer#17547

[tim-harding]

FWIW, I'm still getting this error on 4.26.1, both with the stable and nightly versions of Neovim and rust-analyzer. Won't be around for a couple of days, but I'll try and put together a repro when I get back.

[mrcjkb]

@tim-harding if you post a stack trace, perhaps I can find out if there's been another breaking rust-analyzer change.

[tim-harding]

On further inspection, it seems that the issue is coming from using codelldb instead of codelldb-bin from the AUR. If you see any reports with this sort of thing in the DAP log, they might be the same issue:

[ INFO ] 2024-07-10T15:20:17Z-0700 ] .../tim/.local/share/nvim/lazy/nvim-dap/lua/dap/session.lua:904 ]	"Breakpoint unverified"	{
  id = 1,
  message = "Resolved locations: 0",
  verified = false
}

For clarification, with some Rust and Neovim versions I would see the error from this issue, but usually I was getting a DAP session that would just seem to hang, with no breakpoints hit and nothing in the scopes window. Apologies for the noise in this thread, after hours of trying I thought my issue might be relevant here because I saw the same thing sometimes, but it seems it was unrelated after all.

[Ciel-MC]

I haven't used nvim in a long time, I just came back, fixed lspconfig, but now when I open a Rust file I get this same error, any ideas?

@Ciel-MC are you using the latest version of this plugin?

This is the line #297 that is calling a non-existent pretty_print field, according to your stack trace:

rustaceanvim/lua/rustaceanvim/lsp/init.lua

Lines 297 to 298 in 4b8c2ed

	lsp_start_config.init_options = vim.tbl_deep_extend(
	'force',

A search for pretty_print in this repo yields no results (except for your comment).
So you either have an issue in your config or another plugin is somehow interfering - plus you're likely using an outdated version of rustaceanvim?

Hi, sorry about that. It is the line you highlighted that was the problem. I just tried to print the table out (which ended on the same time) for debugging. The problem is that the table extend’s second argument is nil.
