Hello,
I got error `An unknown error occurred.` when I tried to create feature layer, I freshly registered free developer account and followed tutorial Create a new dataset | ArcGIS for Developers .
Any help how to continue?

Hi Martin Cerank,
You may have resolved this by now, but wanted to see if it's still an issue. If so let me know and I can help get a case going with Esri Support to take a closer look.
Thanks,

Excuse mi later response, after some time it started to work so it is hard to tell, but now it works
