Dependency paths are not resolved py serve-d

[nikolayKeniston]

There is sample project:

dub.sdl:

name "sample"
targetType "library"
dependency "vibe-core" version="~>2.11"

src/test.d:

module test;
import vibe.core.net : TCPConnection;

Which is perfectly build-able with dub build:

Starting Performing "debug" build using /usr/bin/dmd for x86_64.
Building sample ~master: building configuration [library]

With properly resolved paths in dub describe --import-paths:

/home/user/proj/d/test/src/
/home/user/.dub/packages/vibe-core/2.13.0/vibe-core/source/
/home/user/.dub/packages/eventcore/0.9.37/eventcore/source/
/home/user/.dub/packages/during/0.3.0/during/source/
/home/user/.dub/packages/taggedalgebraic/1.0.1/taggedalgebraic/source/
/home/user/.dub/packages/vibe-container/1.7.0/vibe-container/source/
/home/user/.dub/packages/stdx-allocator/2.77.5/stdx-allocator/source/

However, even with a bare require'lspconfig'.serve_d.setup{} in nvim, in test.d the following error is reported for the import statement by serve-d:

1. unable to read module `net`
   test.d:1:7: Expected 'vibe/core/net.d' or 'vibe/core/net/package.d' in one of the following import paths:

The standard library and other features work fine, but not a single symbol from any dependency can be resolved. Judging by the error message, it seems that serve-d does not pick up any of the import paths from dub.
Basic health checks don't reveal any obvious issues, project root in :LspInfo points to right path, all D-related executables are in PATH, etc.

Env:
archlinux
serve-d v0.7.6 with workspace-d v3.7.0
NVIM v0.12.0-dev-934+ga9a4c271b1

Even force setting projectImportPaths (https://github.com/Pure-D/code-d/blob/50ca8ca2831403d50bac10681df87a77b1af1bc4/package.json#L312C1-L312C4) like follows:

            settings = {
                d = {
                    projectImportPaths = {
                        "/home/user/.dub/packages/vibe-core/2.13.0/vibe-core/source/",
                        "/home/user/.dub/packages/eventcore/0.9.37/eventcore/source/",
                        "/home/user/.dub/packages/during/0.3.0/during/source/",
                        "/home/user/.dub/packages/taggedalgebraic/1.0.1/taggedalgebraic/source/",
                        "/home/user/.dub/packages/vibe-container/1.7.0/vibe-container/source/",
                        "/home/user/.dub/packages/stdx-allocator/2.77.5/stdx-allocator/source/",
                    },
                },
            },

does not change anything at all and 'in one of the following import paths' section remains empty, even through it possible that this option doesn't do whatever I think it should do.
