RangeError: Maximum call stack size exceeded

[nverno]

Hi, I'm trying to run the language server using emacs' lsp-mode,
but the server is crashing shortly after starting with the following
stderr output:

Language Server is started.
node:internal/fs/utils:248
function getDirents(path, { 0: names, 1: types }, callback) {
^

RangeError: Maximum call stack size exceeded
at getDirents (node:internal/fs/utils:248:20)
at readdirSync (node:fs:1551:34)
RangeError: Maximum call stack size exceeded
at getAwkFilesInDir (<...>/nodejs/20.7.0/lib/node_modules/awk-language-server/out/io.js:22:26)

Same thing with node versions v18.5.0 and v20.7.0.

Tracing the calls from lsp-mode to the awk language server, it appears
that emacs is receiving a request for 'workspace/workspaceFolders', then
sending its response 'workspace/workspaceFolders' with params:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": [
        {
            "uri": "file:///..."
        },
        etc...
    ]
}

At which point the error happens.
Do you know why this might be? A problem on the lsp-mode side or with the language server?

Running with the --noIndex flag seems to fix the problem, not sure if that should be default in lsp-mode,
or if the server should be able to run without it?
