Script function Solr.contentQuery: unable to select a workspace

The workspace cannot be set anymore because the methode WorkspaceSelector.getWorkspaces() has been deleted.
It is called into the Solr script functions (Solr.js, line 27):

const workspaces = workspaceSelector.getWorkspaces();

Maybe replace it by:
RepositoryDao.getWorkspaces()
or from the session (but I don't know if it works in async mode).
