Hi Maddy,

Thank you for getting back to me. I got this sorted out already.

Thanks!

Can you help me with this one instead?

Reference Type Error

I am getting these error when choosing a Reference type for a new field. In Model Editor: [image] Failed to set value Error: [mobx-state-tree] Value [object Object] is no MST Node In Content Editor: [image] Failed to set value Error: [mobx-state-tree] unprotect can only be invoked on root nodes

I am trying to add new field of type reference, for some reason, i keep of getting the error and i can’t select a value.
