Cannot create categories under Category Root

[jonasboman]

We are experiencing issues as well when trying to create Categories.

Is works locally but not in DXP.

It breaks when using New Item under For All Sites (CategoryRoot).

"Unable to load /EPiServer/cms/Stores/contenttype/?query=getsuggestedcontenttypes&localAsset=false&parentReference=451&requestedTypes=geta.optimizely.categories.categorydata status: 500"

ID 451 would be For All Sites (CategoryRoot) node.

Using version 1.1.1
And CMS 12.25.1
