Server crashes in code-server container

[haohanyang]

Describe the bug
LSP crashes when running in the coder-server container

To Reproduce

• Pull and run the docker image

• In the container, install Erlang and rebar3

# dependencies
sudo apt-get update
sudo apt-get install erlang

curl https://s3.amazonaws.com/rebar3/rebar3 -o rebar3 
sudo install rebar3 /usr/local/bin/rebar3
rm rebar3 

• In the container, clone and build the project

git clone https://github.com/erlang-ls/erlang_ls
rebar3 escriptize
rebar3 as dap escriptize

• In the container, start the LSP

escript _build/default/bin/erlang_ls

Expected behavior
The LSP should start successfully

Actual behavior
Server crashes, it shows

Crash dump is being written to: erl_crash.dump...done

Workaround
Remove custom_snippets/0 in load_snippets/0 in the file apps/els_lsp/src/els_snippets_server.erl(should delete custom_snippets/0 and ensure_dir/1 as well)

-spec load_snippets() -> ok.
load_snippets() ->
    init_snippets_table(),
    % [insert_snippet(S) || S <- builtin_snippets() ++ custom_snippets()],
    [insert_snippet(S) || S <- builtin_snippets()],
    ok.
