rust-analyzer does not have a configuration

[dr-kernel]

When I start up the server, I get these errors sometimes (haven't found a consistent root cause), as time goes on it will eventually fail entirely with this error. Trying to "restart" the server fails with this error. If i restart the editor SOMETIMES it will work but then eventually fail.

 ...m/lsp/client.lua:623	"LSP[rust-analyzer]"	"Cannot find request with id 3715 whilst attempting to cancel"
.../lua/vim/lsp.lua:393	"rust-analyzer does not have a configuration"

rust-analyzer version: latest and currently trying 0.3.2291

rustc version: 1.86 and 1.83

editor or extension: VScode and Nvim (0.11)

relevant settings: VScode (default),
Nvim:

return {
    "mrcjkb/rustaceanvim",
    opts = {
        server = {
            settings = {
                ["rust-analyzer"] = {
                    cargo = {
                        extraEnv = { CARGO_TARGET_DIR = ".ra_target" },
                        features = "all",
                    },
                    check = {
                        features = "all",
                    },
                },
            },
        },
    },
}

These are not errors rust-analyzer emits, so it's likely a problem with your client.

[dr-kernel]

Which client? I reached out to Nvim LSP (the client?) they say its RA's fault...

[ethanuppal]

I reached out to rustaceanvim a while back and they also said it's RA's fault

@ethanuppal the discussion you opened in the rustaceanvim repo does not seem related to this.

@dr-kernel you are using the rustaceanvim client.
Please follow the troubleshooting guide and if you can reproduce it with the minimal config, file a bug report in the rustaceanvim repo.
If you are using a Neovim distro like AstroNvim or LazyVim, please ask there if you can't reproduce with plain Neovim and the minimal config.

[ethanuppal]

@mrcjkb yes, I neglected to mention it in that issue because I didn't think that was the root of the issue (I still can only say it is correlated). I also tried reverting to Neovim 10 and that didn't solve the issue. I think I might need to both revert to Neovim 10 and use an older version of rustaceanvim/rust-analyzer.

[mrcjkb]

Note that the Neovim log entry, rust-analyzer does not have a configuration, is not an error.
Neovim just logs that when a client queries vim.lsp.config['rust-analyzer'] and there exists no configuration specifically for rust-analyzer that was set via the vim.lsp.config API.

Cannot find request with id 3715 whilst attempting to cancel may be an issue with Neovim's built-in LSP client.
