I have a Text field on my Power Pages site that I'm attempting to populate using PowerFX.
This works:
=LookUp(Contacts,Contact=User.DataverseUserId).'First Name'
However, what I actually want to do is something like this:
=LookUp(Contacts,Contact=User.DataverseUserId).'Custom Attribute Record'.'Custom Attribute Name'
When I do this, the output I get is: "Collection was of a fixed size"
How can this be resolved?
