• initImportVars trims a trailing "/" but the subsequent switch only recognizes the default dashboards path when opts.dir == "grafana/dashboards". In the default import flow, validateImport may set opts.dir to filepath.Join(homePath, "grafana/dashboards") (e.g., when HARVEST_CONF is set), which means none of the switch cases match and opts.dirGrafanaFolderMap stays empty—resulting in a no-op import. Consider normalizing opts.dir with filepath.Clean and matching the default case against both the relative and filepath.Join(homePath, "grafana/dashboards") forms (and/or using filepath.Base/filepath.Rel) so the default folder mapping works regardless of HARVEST_CONF or whether the path is absolute.

	// default behavior
	opts.dir = strings.TrimSuffix(opts.dir, "/")

	switch {
	case opts.dir == "grafana/dashboards" && opts.serverfolder.name == "":
		m[filepath.Join(opts.dir, "cmode")] = &Folder{name: "Harvest-main-cDOT"}
		m[filepath.Join(opts.dir, "cmode-details")] = &Folder{name: "Harvest-main-cDOT Details"}
