The debug symbol files are not included into the recent Qt 6.8 qtlanguageserver exports. The last export that contains the debug symbols is

https://ci-files02-hki.ci.qt.io/packages/jenkins/qt/6.8/b12fd026dc3b315de9b20691543445619f03e9f9/debug_information/

Could it be that this is related to https://codereview.qt-project.org/c/qt/qtlanguageserver/+/570546 JSON-RPC/QtLanguageServer: Enforce static builds ?

For all other submodules there are separate debug symbol files are exported under /debug_information folder.

Until this is fixed, we can copy the debug symbols from https://ci-files02-hki.ci.qt.io/packages/jenkins/qt/6.8/b12fd026dc3b315de9b20691543445619f03e9f9/debug_information/  into the latest export folder if a repository build needs to be done from the export (as currently our packaging configuration scripts assume that there are separate debug symbol files also for qtlanguageserver). If this is a feature, please inform the release team (Tarja Sundqvist or Jani Heikkinen) as we need to update our Qt 6.8 packaging scripts then.
