Environment

• Elixir & Erlang versions (elixir --version): 1.10.2 & 22
• Operating system: Ubuntu 18.04
• Editor or IDE name (e.g. Emacs/VSCode): VSCode
• LSP Client name: vscode-elixir-ls
• If using VSCode, are you using "ElixirLS Fork: Elixir support and debugger" (note that it has "Fork" in the name)? I found this issue with both the ElixirLS extensions, and frankly I am not sure which one has the latest code and which of those two I should be using

Troubleshooting

• Restart your editor (which will restart ElixirLS) sometimes fixes issues
• Stop your editor, remove the entire .elixir_ls directory, then restart your editor (couldn't find this directory)

Crash report template

Delete this section if not reporting a crash

1. If using a client other than VS Code, please try VSCode's "ElixirLS Fork: Elixir support and debugger" extension. Does it reproduce your failure? Yes both the vscode extensions give me the same error and I disable one of them while running the other

2. Create a new Mix project with mix new empty, then open that project with VS Code and open an Elixir file. Is your issue reproducible on the empty project? If not, please publish a repo on Github that does reproduce it.

It gave the same error

1. Check the output log by opening View > Output and selecting "ElixirLS" in the dropdown. Please include any output that looks relevant. (If ElixirLS isn't in the dropdown, the server failed to launch.)
   Here is the output

2. Check the developer console by opening Help > Toggle Developer Tools and include any errors that look relevant.
