"property 'dimension' does not match pattern"

[Miha_P_]

I'm trying to add

a new Catalog item to my IoT Analytics. Under My Account, I select a Catalog tab and click "Add New Catalog Item". The form opens, I fill it, and I get an error when saving.

The error I get is "property 'dimension' does not match pattern", but there is no property called "dimension" in the form. What am I doing wrong?
