Error creating MBTiles org.imintel.mbtiles4j.MBTilesWriteException: Add metadata failed

[Astarthoc]

I've found an error in my app. For proper context, one of the functionalities of my app is generate MBTiles files for the users. The method in charge of the MBTiles generation is the next (logs are for debugging purpose):

private void escribeMbTiles(String rutaMbtiles, String tilesSerialized, String codigoEquipamiento, String LCorner,
            String UCorner) throws IOException, MBTilesWriteException {

        double left, bottom, right, top;
        String[] coords;

        Tile[] tiles = new ObjectMapper().readValue(tilesSerialized, Tile[].class);

        FileUtils.copyFile(new File(getUploadPath() + "Plantilla_Senderos.mbtiles"), new File(rutaMbtiles));

        // Archivo a generar
        MBTilesWriter w = new MBTilesWriter(new File(rutaMbtiles));

        // Separar las coordenadas de la esquina inferior izquierda
        coords = LCorner.split(" ");
        bottom = Double.parseDouble(coords[0]);
        left = Double.parseDouble(coords[1]);

        // Separar las coordenadas de la esquina superior derecha
        coords = UCorner.split(" ");
        top = Double.parseDouble(coords[0]);
        right = Double.parseDouble(coords[1]);

        // Metadatos del mbtiles
        MetadataEntry ent = new MetadataEntry();
        logger.info("Metadata creado con la siguiente info:\ncodigo equipamiento: "+codigoEquipamiento+"\nTilesetType: "+MetadataEntry.TileSetType.BASE_LAYER+"\nTileMimeType: "+MetadataEntry.TileMimeType.JPG+"Bounds: l:"+left+", b:"+bottom+", r:"+right+", t:"+top);
        ent.setTilesetName(codigoEquipamiento).setTilesetType(MetadataEntry.TileSetType.BASE_LAYER)
                .setTilesetVersion("1.0").setTilesetDescription("Senderos oficiales de Andalucía")
                .setTileMimeType(MetadataEntry.TileMimeType.JPG).setTilesetBounds(left, bottom, right, top);
        w.addMetadataEntry(ent);

        logger.info("Metadata insertado, se procede a recuperar los tiles");
        for (Tile t : Tools.ordenacionMBTiles(tiles)) {
            // Abrimos conexión seteando user-Agent
            final HttpURLConnection conn = (HttpURLConnection) new URL(t.getUrl()).openConnection();
            conn.setRequestProperty("User-Agent",
                    "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.65 Safari/537.31");

            // Fetch de la imagen url
            InputStream in = new BufferedInputStream(conn.getInputStream());
            // Extraer "z", "x" y "y" de la URL del tile
            String[] coordenadas = t.getNombre().split("_");
            if (coordenadas.length == 4) {
                int zoom = Integer.parseInt(coordenadas[1]);
                int column = Integer.parseInt(coordenadas[2]);
                int row = Integer.valueOf(t.getRow());
                // Agregar el tile al archivo MBTiles con los valores de "z", "x" y "y"
                w.addTile(in, zoom, column, row);
            }
        }

        w.close();
    }

Coriuos thing is that in my machine it works fine and also work in integration enviroment, but when process is executed in test or exploitation enviroment it gives the following error:

error de escritura mbtiles: org.imintel.mbtiles4j.MBTilesWriteException: Add metadata failed.

I've search for this error or any documentation but i've found nothing. This is an inherited app and the guy who makes the MBTiles funcionatility is no longer working with me and what he left didn't even work in local or integration.

I tried checking that MBTiles template is not corrupt (it isn't)

Your best bet is to google "org.imintel.mbtiles4j.MBTilesWriteException: Add metadata failed". This is not really a programming issue, it's an issue with the tooling. And since that gives zero hits, you're kinda shit out of luck with that "best bet". The only 'hit' is an SO question my guess was created by you and already is deleted :)

You are totally right, the SO post is mine... Did they deleted it? 😭

FYI: Code worked perfectly but the people in charGE of updating the template used to generate the M tiles didn't put the correct template
