We are currently experiencing some operational issues on na1.secure.gooddata.com. While trying to create a new data structure (Logical Data Model) or update an existing one, the error would be displayed. This unfortunately applies to the creation of the new GoodData for Zendesk projects too. The existing projects that are not changed in a structural way were not affected.
We are currently working on bringing back the normal functionality and we apologize for the inconveniences here.
