issue with listing users with Graph People

Question

Hello all
We are using MS Graph to tag users in our app. For the last 2 weeks we have been having some problems. Some users don't show up on the tagging list. Anyone having similar issue?

Here is the call we use
https://graph.microsoft.com/v1.0/users/?$filter=(startsWith(userPrincipalName,'bob') or startsWith(displayName,'bob') or startsWith(mail,'bob') or startsWith(surname,'bob')) and userType eq 'Member' and accountEnabled eq true&$top=5&$select=id,displayName,givenName,surname,jobTitle,mail,mobilePhone,officeLocation,preferredLanguage,userPrincipalName,department,createdDateTime,activatedAt

We solved the issue:

It was the UserType that was incorrect, the user had an empty/null UserType. This is very unusual and invalid data, it happened because it was an old account (2012), and this property was created in 2014. We requested the client to update this property and it fixed their issue.
