Unable to SetContents

[MRB60]

I get an empty editor area after SetContents. Suneditor v2.27.0. Also tried with a simple string. No success.
It could be that I have old incompatible config settings and if so, it would be great if someone can point out what has changed between 2.26.0 and 2.27.0.
Code:

this.suneditor = SUNEDITOR.create((document.getElementById('suneditor') || 'suneditor'), this.editorconfig);
this.suneditor.setContents(HTMLeditorcontent);
// register event handler so we can track if data is changed
this.datachanged = false;
this.suneditor.core.history.reset(true); // history stack reset
