Additional context

Oh never mind, I was used Blockly v2 function that was deprecated. Found this on the blockly source code
Blockly.Block.obtain = function(workspace, prototypeName) { console.warn('Deprecated call to Blockly.Block.obtain, ' + 'use workspace.newBlock instead.'); return workspace.newBlock(prototypeName); };
