pyright-langserver stops working after lsp-exit

[tone]

I'm observing that when kakoune starts, I can make use of pyright-langserver functionality, but as soon as the LSP server is restarted (I don't really know exactly when this happens, but I can intentionally make this happen using :lsp-exit), nothing works anymore. It looks like the difference is that after :lsp-exit, pyright-langserver is no longer able to find any source files. My workaround for now is doing :lsp-disable and :lsp-enable...

I have reproduced this with the following minimal kak-lsp configuration:

[language.python]
filetypes = ["python"]
roots = ["requirements.txt", "setup.py", ".git", ".hg"]
command = "pyright-langserver"
args = ["--stdio"]

and the following minimal python file:

class Foo(object):
    pass

class Bar(Foo):
    pass

Here is a set of logs I collected, search for XXX to see the markers I inserted after certain steps were taken: kak-lsp.log.

kak-lsp version is kak-lsp 14.2.0-snapshot.

Interesting, I can reproduce. Running pkill node instead of lsp-exit also reproduces.

It looks like the server sends an invalid (empty) URI

"workspace/configuration","params":{"items":[{"scopeUri":"",

even though we did send textDocument/didOpen earlier so it should know about the file URI.
Might be an issue in pyright.
