g:ale_filename_mappings doesn't work for elixir-ls

[giddie]

Information

VIM version NVIM v0.4.4 Build type: Release

Operating System: ArchLinux

What went wrong

With the following config:

let g:ale_filename_mappings = {
\  'elixir-ls': [
\    ['/home/dannpg/Work/project', '/opt/app']
\  ]
\}

I see the following output from elixir-ls:

{"jsonrpc":"2.0","method":"window/logMessage","params":{"message":"\n10:29:34.893 [error] GenServer ElixirLS.LanguageServer.Server terminating\n** (File.Error) could not set current working directory to \"/home/dannpg/Work/project\": no such file or directory\n    (elixir 1.10.3) lib/file.ex:1523: File.cd!/1\n    (language_server 0.6.2) lib/language_server/serve ...

If I set:

let g:ale_lsp_root = {'elixir-ls': '/opt/app'}

Then elixir-ls operates OK, but it reports the docker paths (/opt/app), so Vim is unable to jump to the correct file.

Any pointers or ideas where I should start looking in the code to solve this?

I am also seeing this for ccls. I have the following:

let g:ale_c_ccls_executable = "./ccls-wrapper.sh"
let g:ale_linters = ['ccls']
let g:ale_filename_mappings = {
\ 'ccls': [
\   ['/home/random/acc/eit/lpwan/lab2/pingping', '/data'],
\ ],
\}

The following is ccls-wrapper.sh:

#!/bin/sh
exec docker run -i --rm -v "$(pwd):/data" -w "/data" contiki ccls --log-file=ccls.log $@

ccls.log:
