Username() and UserPrincipalName() returning an error for some users

[Anonymous]

I have an Azure SSAS taular model deployed maing use of UserPrincipalName() function for its security model.

For some users, this has been causing problems, so I created two measures in the tabular model to get the root of the issue;

whoami:= Username()

whoami2:=UserPrincipalName()

I deployed the model and published a Power BI app with a report containing both measures in two separate visuals.

For a certain user, this creates an error (at the bottom of this post).

However, when I do the same process but in a Power BI dataset, the measures work fine.

What is the cause of the error in the context of the Azure SSAS tabular model?

Fields that need to be fixed
Something's wrong with one or more fields: (Unified Security) whoami
