Now it's working! Thank you for your help!
The modified code:
getTemplate( templateName )
{
let templateFile = this.baseURL+'templates/'+templateName+'.html';
return new Promise(function(resolve, reject)
{
let templateRequest = Polymer.Base.importHref(templateFile,
function()
{
Polymer.dom(document.getElementById('templates')).appendChild(templateRequest.import.body);
resolve(templateRequest);
},
function(error)
{
reject(error);
});
});
};
