It works for me.

Your neovim and deno are not latest. Please update it. nvim-lspconfig must be the latest.

Why don't you execute :mes to print full messages?

And you have not uploaded real minimal vimrc. Note: The statusline is customed in your screenshot.

My vimrc is:

  set nocompatible
endif

The minimal vimrc does not means your ddc configuration part. It must be executed by nvim -u minimal.vimrc.

We have not ESP skills.

Hi!

I was not aware of the :mes command, very helpful, thank you!

As for the complete error, there it is:

It was produced with your minimal vimrc (I updated nvim and deno to latest).

[phgz]

I checked about the error, and it says it might be because of a proxy server issue, but I can use DDC correctly with other sources like treesitter or around.

Also, if I execute deno run https://deno.land/std/examples/welcome.ts, I get:

Download https://deno.land/std/examples/welcome.ts
Warning Implicitly using latest version (0.114.0) for https://deno.land/std/examples/welcome.ts
Download https://deno.land/std@0.114.0/examples/welcome.ts

Welcome to Deno!

Output of deno --version:

deno --version
deno 1.16.1 (release, x86_64-unknown-linux-gnu)
v8 9.7.106.2
typescript 4.4.2

I'm not an expert at Deno, maybe you can point me in the right direction.

[Shougo]

It seems the server certificate problem. So it is not ddc or ddc-nvim-lsp problem. I cannot fix the problem. I have not ESP skills.

[Shougo]

It works for me.

import {
  add,
} from 'https://x.nest.land/arithmetic4@0.1.1/mod.ts'

console.log(add(1, 2));

[Shougo]

I checked about the error, and it says it might be because of a proxy server issue, but I can use DDC correctly with other sources like treesitter or around.

Yes, because ddc-nvim-lsp source only uses equal module. Please see the dependency list.

equal -> fonction -> equal

[Shougo]

And why I use equal module instead. Please read this.

https://github.com/Shougo/ddc-nvim-lsp/pull/13

[Shougo]

I have removed equal module. Please update to the latest.
