Am new to cartodb and am following this tutorial (http://docs.cartodb.com/tutorials/create_map_cartodbjs.html) on how to create a map.

When Implement the sql query, i get an error on the console saying "Failed to load resource: the server responded with a status of 400 (Bad Request)". I have included the screenshot of my browser displaying the error.

 var subLayerOptions = {
  sql: "SELECT * FROM my_cartodb_table_title WHERE city = 'CITY X' "
}


cartodb.createLayer(map, layerUrl/*, {no_cdn: true}*/)
.addTo(map)
.done( function(layer) {
  layer.getSubLayer(0).set(subLayerOptions);
  data_layer = layer.getSubLayer(0);
})
.error( function(err) {
  console.log("some error occurred: " + err);
});


      }

What could be the problem?

The request of your tiles is not being done correctly: check that the URLs you're showing include undefined as identifier.

This is probably caused by using CartoDB.js 3.11.23, which is a quite old version at the moment. The last version of 3.11 is 3.11.38 at this moment and it can be obtained with these URLs.

http://libs.cartocdn.com/cartodb.js/v3/3.11/themes/css/cartodb.css http://libs.cartocdn.com/cartodb.js/v3/3.11/cartodb.js

3.11 for HTTPS:

https://cartodb-libs.global.ssl.fastly.net/cartodb.js/v3/3.11/themes/css/cartodb.css https://cartodb-libs.global.ssl.fastly.net/cartodb.js/v3/3.11/cartodb.js

Right now, the last CartoDB.js release is version 3.15, whose URLs are the following ones:

http://libs.cartocdn.com/cartodb.js/v3/3.15/themes/css/cartodb.css

http://libs.cartocdn.com/cartodb.js/v3/3.15/cartodb.js

3.15 for HTTPS:

https://cartodb-libs.global.ssl.fastly.net/cartodb.js/v3/3.15/themes/css/cartodb.css

https://cartodb-libs.global.ssl.fastly.net/cartodb.js/v3/3.15/cartodb.js

If you're using the non-versioned URL for CartoDB.js (http://libs.cartocdn.com/cartodb.js/v3/cartodb.js ), you need to be aware that this non-versioned URLs are deprecated and should be no longer used, but you need to specify the version you want in the URL.

  • Hi, again. In my css code, just after my sql statement I added this line cartocss: "#table_title{marker-fill : #6d1948; marker-width: 5; marker-line-color: white; marker-line-width: 1; }" and I get an errors in the console. 1. Uncaught SyntaxError: Unexpected identifier 2. Uncaught ReferenceError: init is not defined I have declared the function init here <body onload="init()"> What could be the problem. Many Thanks! – 1088 Jul 9 '15 at 15:50
  • If it's a different question, could you open it as a new one? :) – iriberri Jul 9 '15 at 16:55
