Did you put this code into event_player_activated? If not the code was maybe not loaded properly and you need to logut and back in.

You could try to use functions like these here to get the zone info too:

* GetCurrentMapIndex()
** _Returns:_ *luaindex:nilable* _index_

* GetMapIndexByZoneId(*integer* _zoneId_)
** _Returns:_ *luaindex:nilable* _index_

* GetCyrodiilMapIndex()
** _Returns:_ *luaindex:nilable* _index_

* GetImperialCityMapIndex()
** _Returns:_ *luaindex:nilable* _index_

* GetCurrentMapZoneIndex()
** _Returns:_ *luaindex* _zoneIndex_

* GetZoneNameByIndex(*luaindex* _zoneIndex_)
** _Returns:_ *string* _zoneName_

* GetMapNameByIndex(*luaindex* _mapIndex_)
** _Returns:_ *string* _mapName_

* GetNumMaps()
** _Returns:_ *integer* _numMaps_

* MapZoomOut()
** _Returns:_ *[SetMapResultCode|#SetMapResultCode]* _setMapResult_

* WouldProcessMapClick(*number* _normalizedClickX_, *number* _normalizedClickY_)
** _Returns:_ *bool* _wouldProcess_, *luaindex:nilable* _resultingMapIndex_

* ProcessMapClick(*number* _normalizedClickX_, *number* _normalizedClickY_)
** _Returns:_ *[SetMapResultCode|#SetMapResultCode]* _setMapResult_

* GetMapInfo(*luaindex* _index_)
** _Returns:_ *string* _name_, *[UIMapType|#UIMapType]* _mapType_, *[MapContentType|#MapContentType]* _mapContentType_, *integer* _zoneId_, *string* _description_

* GetZoneDescription(*integer* _zoneIndex_)
** _Returns:_ *string* _description_

* GetZoneNameById(*integer* _zoneId_)
** _Returns:_ *string* _name_

* GetZoneDescriptionById(*integer* _zoneId_)
** _Returns:_ *string* _description_

* GetMapParentCategories(*luaindex* _index_)
** _Uses variable returns..._
** _Returns:_ *string* _categoryName_, *luaindex* _categoryIndex_

* GetMapNumTiles()
** _Returns:_ *integer* _numHorizontalTiles_, *integer* _numVerticalTiles_

* GetMapTileTexture(*luaindex* _tileIndex_)
** _Returns:_ *string* _tileFilename_

* GetMapName()
** _Returns:_ *string* _mapName_

* GetMapType()
** _Returns:_ *[UIMapType|#UIMapType]* _mapType_

* GetMapContentType()
** _Returns:_ *[MapContentType|#MapContentType]* _mapContentType_

Maybe the map texture names somehow use a pattern that say "We are in a house now". And you can read it from there in event_player_activated,
